Mobile Suit Gundam Age/WMG

Gundam AGE (the mobile suit) is based on a Gundam from a previous AU.
In just the first episode, Flit is told by his butler (in a flashback) that Gundam is a saviour that put an end to wars in the past, and that it has been passed down in the Asuno family for many generations. Sound familiar?
 * Judging from what we've seen so far in terms of the characters and the attitude of the show, if it is based on another AU, it's most likely the After War universe. Let's hope this doesn't get Screwed by the Network or by the fanbase like Gundam X.

The UE are rogue AI
This would help explain how they showed up out of no where and why their attack pattern can apparently be predicted with math
 * Jossed. They're actually

=== How can there be three generational protagonists in a single series that covers 100 years? Simple, Flit and Asemu will die after losing to the Big Bad. === Much like Infinity Blade, the future sons will be driven to avenge their fathers. This will require them having to further develop the AGE system through experience in battles against the UE. Eventually, Kio (the third son) will have enough experience and skill to be the one who finally takes down the Big Bad. The fact that a game studio is co-producing the series adds further reason for this.
 * Jossed. The series follows Flit's life throughout the three generations this series covers.

Gundam AGE is a prequel to Turn a Gundam; or at least, a more direct prequel than every other series
One of the very first things you see in the first episode is a Union officer walking alongside an HRL officer, meaning that Mobile Suit Gundam 00 happened some time in AGE's past. But looking at Flit's little flashback to the painting of the Gundam, his butler mentioned that the Asuno family has been building mobile suits and Gundams for generations... meaning that they're the heirs/descendants of Anaheim Electronics.
 * And maybe Woolf is one of Loran's predecessors? He does look particularly much like Loran, he pilots a while Mobile Suit and his uniform on the ship looks a lot like Loran's Pilot Suit.
 * Coming to think of it, that actually makes sense. Not only do we have a character that looks an awful lot like the hero from Turn a Gundam, but we also see a legendary mobile suit returning to save mankind (which would fit the events of AGE right after Endless Waltz.)  Judging from the above and the sheer number of Mythology Gags, AGE could very well be a prelude to the Moonlight Butterfly incident.

The UE are human beings who have returned to the Earth Sphere in order to get revenge for their ancestors having been driven into deep space.
During the war torn past of the A.G. one of the factions was either driven out of or fled the Earth Sphere. They settled in deep space most likely around Jupiter, assuming no FTL. In the following centuries these people developed a completely different culture and technological design aesthetic. Somebody or bodies high up in the U.E government wasn't happy with their deep space civilization. And wanted to get revenge/justice on the Earth Federal Government. They declared war on the EFG, and have deployed advanced scouts to test the military capabilities of the Earth Federal Forces. And strike terror in the hearts of the EFG populace in preparation for a full scale invasion.
 * Gee, that sounds familiar. Speaking of which...
 * Close.

Yurin is an UE agent.
That explains why she was afraid of the Gundam initially, appeared seemingly out of nowhere in an evacuated colony, and knew about the tunnel that was going to be bombed.
 * She's not an agent...but one or both her parents are. Which will cause all kinds of trouble when becomes she aware of her heritage.
 * Perhaps this is taking a trailer a bit far, but the preview for episode 11 does show Yurin crying on Flit, so she could be a pilot who might have to go against Flit one day. Gundam is not known for being kind to couples, so this wouldn't be the first time we see this.

The U.E. are all X-Rounders/Newtypes out for Revenge against the Earth Sphere.
In the past of the A.G. there was a moderate sized population of X-Rounders. And their abilities were exploited by all the waring factions. X-Rounders were forcibly conscription into the government/military because they were regarded as to dangerous and useful to be left to their own devices. The X-Rounders on all sides got sick of this treatment and they rebelled. All the factions united under the banner of the Earth Federal Government. To Form a united front against the X-Rounder rebellion. With the aid of a Gundam Pilot(who may have been an ancestor of Flit Asuno) the EFG won the war. And the Rebel X-Rounders along with their friends family members and allies all fled into deep space.

In centuries following the war people in Earth Shpere mostly for got about X-Rounders and the technologies that were related to them were discarded;Psy-commu. Psycho-Frame. Bits and Funnels.
 * Given Geera Zoi's words in episode 15, the UE are not populated by X-Rounders, as he worries about going up against Flit, a true X-Rounder, in battle.

Yurin and Desil are going to die.
Their only presence in the opening is as transparent images that appear right after the image of Flit's mother. Who is dead.
 * While Desil will likely survive Flit's arc, Yurin might not be so lucky. A melancholic character song? Check. A montage of romantic scenes in the outdoors? Check. A butterfly leading Flit to Yurin a la Lalah's swan? Check. A preview showing the Big Bad trying to manipulate the girl? Check. All in all, it seems that the Love Hurts tradition of Gundam is going to strike again...
 * Moreover,

Desil is going to be the Big Bad and take the Enfante Terrible trope to the max.
It will be a cool twist if Yark Dole, who is being set up as a sinister and mysterious character, turns out to be a Red Herring and that he follows Decil's orders and not the other way around. Moreover, we've seen how talented Decil is as a mobile suit pilot, so it would provide a much bigger threat to the Diva if he was the boss of the UE or whoever will be the true enemy.
 * Jossed. He's The Dragon for the UE and an Ax Crazy Blood Knight Dragon at that.
 * At least you're right about Enfante Terrible to the max.....

The AGE System is Devil Gundam.
A machine that works on the same principles as natural evolution? Let us hope it never turns evil.

The UE's mission is to force humanity back to Earth.
Which is why they want to terrorize people to abandon their colonies rather than destroying them outright. Thus making their plan a reverse of Char's.
 * Nope.

The UE is not trying to fight humanity, but force them to become stronger
Why else would that UE mobile suit stop and retreat right when Flit imposes himself in its path? It's the same reason why they didn't outright destroy Nora given several chances; rather than kill them, the UE is inflicting damage in order to force humanity to overcome adversity, and thus become stronger in order to be ready to fight some other stronger unknown enemy in the future.
 * That... That actually sounds kinda plausible. Why kill a powerful enemy, when you can instead make them a potentially even more powerful ally?
 * However, in episode 13, the UE are shown to have nothing but utter contempt for humanity, which makes this theory less likely.
 * Jossed.

Flit and/or Asem will perform a Face Heel Turn at the end of their arcs.
Said will make up Asem/Kio's major motivation for fighting the UE.
 * Probably won't happen. We have yet to see a Gundam main character do a Face Heel Turn (except in Wing, where everyone changed sides all the time).
 * Jossed. Flit hates the UE now more than ever.
 * If his hatred towards the UE is anything to go by, Flit is becoming fanatical about the Earth Federation's cause. And remember that the Earth Federal Forces are corrupt and genocidal, which makes them no better than the UE...

Flit and Yurin will get together at the end of the first story arc.
The design of Asem in concept art is a throw-off to make us believe that Flit and Emily will get together rather than Flit and Yurin. It may also be possible that isn't even Asem's final design, and is either a false design used as a ruse to prevent spoilers or an early design from when the Official Couple was different. Wishful thinking...
 * Take a close look at Asem's eyes from the latest ads promoting the second generation and compare that to Yurin's eyes. It seems that this theory could very well be the case, making this Asem's first designs as a clever example of Never Trust a Trailer.

The announcement that JAM Project will be doing the opening to the show was not false.
Anime series tend to have multiple openings, and many anime series add in a more intense opening to match the dire situations later in the show. As such, Galileo Galilei's calm and collected opening will be replaced by JAM Project's inevitably intense, hard-rock opening when the story ramps up. Or, alternatively...
 * Jossed REALLY hard. As Sunrise can't hire them to do the songs mainly due to high licensing issues.

There will be an opening and ending representing each story arc and its main character.
Each story arc will feature a new opening that matches the ideals and dispositions of the featured protagonist. The current opening by Galileo Galilei is level-headed and determined, matching Flit's personality to a T. When Asem takes center-stage from his father, the opening will change to more of an intense, headstrong, hard rock ballad to match. Kio will also have an opening fitting his personality.

Gundam AGE will become self-aware.
Come on! It's a mobile suit that's designed to evolve like an organic entity as it accumulates experience. You just know that at some point it's going to develop thoughts and will of its own.
 * Which would explain why the U.E. are attacking. They realize the threat of the Gundam AGE-01 and want to destroy it before it becomes a larger threat.

Gundam AGE is centuries after Gundam Wing
Think about it. Its said that Mobile Suits were abandoned centuries ago until the UE arrived. And that Gundams used to protect things. Its getting blatantly obvious now.

How will Desil react to the fact that Flit is an X-Rounder?
We all know he'll figure it out eventually.

X-Rounders are the UE
They seem to be humanlike but they are not original humans from Earth.

The first part of the series is going to end with a downer Wham! Episode.
Yurin, as well as tons of supporting characters, die and the Diva and Age-1 both get wrecked. Moreover, the U.E. will be successful at whatever their doing. But Flit escapes with the AGE system, and swears that "One day, my descendents and the Gundam will be your doom!"
 * Well,

Each part of the series will be heavily lifted from an older Gundam series.
The first part owes a fair amount to Mobile Suit Gundam: Flit bonds with the show's Lalah Sune Expy and said Expy goes the Lalah way as well. The battle for Ambat rather resembles the one for Solomon too (complete with Big Zam Expy in the closing moments of episode 14)... things will probably end with a final duel (hopefully to the death) between Desil and Flit. And in the final part of the show, the UE will turn out to be Coordinators. Who knows?

The Earth Federal Forces will be enemies in Part 2.
The Federation's cover-up of is what led to the war in the first place, and they clearly haven't learned by their treatment of. In order to stop the cycle from repeating itself, they'll have to fight against the Federation itself and expose the corrupt elements, much like what happened in Zeta Gundam. Of course, they'll still have to fight the UE, and it may even culminate in a Melee a Trois at the end.
 * Jossed. Asemu is a pilot for the Earth Federal Forces. Though that Melee a Trois part might be correct if that Company man from episode 23 has anything to do with the conflict...

Flit will be forced to face-off against Asem.
It's clear that Flit will always hate for as long as he lives. However, Asem might see and understand the plight the martian colonists face. It would thus be very interesting to see Asem, Millais, and the Diva crew turn on the Earth Federation and become a third side, which would surely result in Asem having to fight against his own father's forces.
 * Jossed.

Groodeck will return in the second generation.
He's only in jail, and he's also got more experience fighting the UE than anyone else. The Federation just might give him a special pardon when the UE rears its ugly head again, just so they can get at his experience.
 * Better Rejoice, the preview of Episode 23 shows an older Flit talking to a much older and now free Groodeck.

Veigan's goal is total extermination of the entire Federation.
So far, Veigan has mostly attacked civilian colonies with no Federation military presence. Flit also reveals in episode 16 that the Federation has sued for peace multiple times, but Veigan has refused all of their offers. Veigan's ultimate goal could be a Final Solution regarding all humans who were born and raised in the Earth Sphere, at which point the Mars colonists would settle the planet.

Kio's mother/Asem's wife is Romary.
Based on Gundam Age's law of genetics, the son will take on his mother's hair colour and style(applicable only to generations after Flit). Asem clearly has Emily's blonde hair and that signature plaid then she still has, although far more flamboyant. Kio has brown hair and a style akin to what Romary has now. Also oddly creepy as Romary resembles Flit's mother heavily.
 * This was pretty much confirmed before the show began.

On the other hand, he's the sister's son
Asem has been shown to be willing to take risks to save even people he doesn't care for much, so he may die sacrificing himself. This would spur Flit on and possibly start to inspire peace with others.
 * Jossed. The magazine confrimed that Kio is Asemu's son.

Desil will backstab Zeheart
It's very obvious that Desil resents Zeheart for having a higher rank than him, and he even makes an offhand threat about revealing the true reason why Zeheart failed to destroy the Gundam in Episode 20. At some point, he's going to try and oust Zeheart and take his place as Commander of the Earth Occupation Forces.

Frederick is the Vagan spy
As the Number Two to Flit Asuno, Frederick seems way too good to be true. If the above is true, then he is using his position as a strategist to give the Earth Federal Forces minor victories, all the while preparing for one, massive Vagan victory. Moreover, his Sorting Algorithm of Face Heel Turning resulted in a 3.8, which makes his likelihood of being a Vagan considerably high.

The reason Descil and Zeheart could not sense Asemu in episode 26 was because the helmet in episode 25 only fried the part of Asemu's brain that connects to other X-Rounders.

 * This seems unlikely as of episode 27. Zeheart's issue with fighting Asemu was that he was just too damn fast, not that he was unreadable.

Asemu will go into a vegetative state by the end of the Second Generation
This would be a perfect nod to Zeta Gundam and a fitting way to set the table for the Third Generation. But wait, how will Kio come into the world? Simple: While Asemu is in a vegetative state, The Company/Illuminati man from episode 23 will grab Romary and use her to create Ace Pilots with Asemu's genes, not unlike the Les Enfants Terribles Project.
 * Now that was uncalled for!
 * Now that was uncalled for!
 * Now that was uncalled for!

The former Federation Prime Minister isn't actually dead.
The narration explaining how is merely misinformation, since Flit specifically states that he wanted all of the information the prime minister had.

Ezelcart will attempt to recruit Kio
Think about it. Who've been the main thorns in the Vaigan's side all this time and almost the entirety of why everything hasn't been going All According to Plan? The Asunos. Think about it. Imagine if he took the only force capable of opposing him and made it his own?

Ezelcant is Flit's father.
Now hold on, how could Fezearl Ezelcant, the leader of the nation Flit wants to exterminate, possibly be related to the Asuno family? He will show himself in front of Kio and, like most Gundam shows, will show his masterstroke to The Hero. During this, he will reveal that he wants his family to gain control of the system. Cue a flashback showing Marina Asuno meeting a young man in her past and falling in love with him. During this, he would eventually disappear, leaving her and her young son behind. Pardon this troper's George Lucas-calibur line, but in the end, she will probably say, "Come back to us... Fezearl," followed by the reveal of the AGE-0, the Original Gundam...
 * Well, the third opening
 * UPDATE:

In the third generation
The third opening features At some point during the third generation (likely near the halfway point)  This will likely be accompanied (or followed) by a new OP and the start of the final part of the story.
 * As of the beginning of the third generation
 * It seems more likely that

During the Third Generation, Veigan's entire motives will be revealed to be a big ol' lie
From the shot of what life in their capital actually is, its possible that the so called catastrophe that gave birth to Veigan was not as bad as it seemed, or was GREATLY exaggerated. Ezelcant took advantage of this to form a fighting force completely loyal to him that would do anything he said. This'll be revealed mid to late way through the generation, causing many Vagans to throw down arms.
 * Episode 33 adds a little credence to this theory.

Asemu is not the pilot of that black Gundam AGE-2 from the opening.
Given that the symbol from the OP is from Visidian. Also, Asemu did join forces with Wivik, a member from Visidian, and he went missing after that. It's quite possible that this black Gundam AGE-2 is actually a tribute to Asemu.

Asemu will become a Captain Harlock expy in the Third Generation.
Complete with his own Eye Patch of Power and his own equivalent of the Arcadia.

A theory about future events in the Third Generation.
Currently such a development is highly unlikely, but it will be a nice surprise if it actually happens.

There will be
Early promotions for the shows says that the war will go on for around 100 years. Sunrise revealed almost every detail about the series (mostly on the Gundams, but still), but they probably want to keep this one detail under wraps.

Wivik Lambro will return
Captain Ash is commanding one ship ther may be two the other is piloted by Wivik the two will possibly form a big Big Damn Heroes later and save the day with a revelation on the cursed treasure


 * Because of the war or other events maybe joining in in with ash Kio will join them bringing the AGE System along as well.

Flit will undergo a Heel Realization which will lead to both a My God, What Have I Done? and Redemption Equals Death scenario
At some point during the third generation, Flit is going to realize how much his obsession with destroying Vagan has cost him and what it's driven him to do, or that Yurin would never have wanted him to do the things he's done to avenge her death, especially where his family is concerned. Realizing this will lead to Redemption Equals Death, possibly during one last battle with the AGE-1 (which will naturally be wrecked in the process). His last words will probably be an apology to either Asemu or Kio (or both, depending) for not being a better father/grandfather. Or maybe he'll have a vision of Yurin, waiting for him. Either way it'll probably be a massive Tear Jerker.
