Smile Pretty Cure/WMG

The Smile Cures' Super Mode will have "Ultra" tacked in before their Cure names (such as Ultra Cure Happy) as a reference to Miyuki's Catch Phrase.
They already did "Super" with Yes! Pretty Cure 5 (first season) and Heartcatch Pretty Cure...

The season will be a Reconstruction of the Magical Girl Warrior genre
The reason is that many anime viewers last year just watched the Deconstruction Puella Magi Madoka Magica, which picked apart many essential Magical Girl tropes. Thus, this year Toei will do what Tengen Toppa Gurren Lagann did for the Humongous Mecha genre and make Smile Pretty Cure more Troperiffic than any of their past seasons.

Two more Cures will join the team, and their elements will be earth/metal and darkness.
There's seven little gems in the transformation device and the town's name is translated as "Seven Prismatic Colors". And going with how each cure has an element, the purple cure may use darkness to be a contrast to Miyuki's light powers.
 * Dark power is usually associated with evil, so probably not. Also, technically Cure Peace IS earth to an extent (she uses lightning, but lightning is a part of weather which affects the Earth.) A red Cure could have powers like Heart/Love, while a purple Cure could have something like Soul.
 * Evidently, Cure Sunny's case may be similar to that of Cure Muse (who had a purple Fairy Tone and a yellow color scheme). She uses a Red Decor and the Smile Pact glows red during the transformation, but her overall image color is orange. There are three different warm colors on the pact (one of which belongs to Cure Sunny): yellow (Cure Peace), amber/gold, and red/orange. So either way, the Sixth Ranger Cures being purple and amber/gold is still legit.
 * The element of Darkness worked for Sailor Saturn I believe. A shame they may not be able to do that in Pretty Cure to explain that Dark Is Not Evil.

Midway during Smile Pretty Cure, Reika/Cure Beauty will fall in love with a monster or a villain.
Fairy tale thematic, Beauty and The Beast, natch.

Cure Sunny's Mid-Season Upgrade changes her color from orange to red. Another member changes to Purple for their Mid-Season Upgrade.

 * Sunny's Cure Decor is orange...but the light is red.
 * In the title eyecatch, Sunny holds a red and orange balloon.
 * There are 7 lights in the Smile Pact (which fits with the rainbow theme), and it's the red one that glows when she transforms. The unaccounted for ones are purple and orange(/gold?).

Pierrot is the Final Boss.

 * He won't appear until episode 22 at the earliest. Refer to the countdown clock of doom shown during each episode when the villain appears. The appearance delay means he's more likely to be the real Big Bad.
 * Sabaku and Mephisto appeared much earlier in their respective seasons of Heartcatch Precure and Suite Precure.

Cure Sunny will have a seperate exclusive Super Mode coloured orange.
There. Problem solved.

At one point in the show there will be some lampshading on Wolfrun and Miyuki being shipped together.
I think in one episode when the cures become really popular and the public take notice of the bad guys; there will be a fan following pairing up Cure Happy and Wolfrun.Their reactions will very much be a Crowning Moment of Funny.

The two remaining gems on the Smile Pact represent combo attacks.
For instance, Cure Happy (Pink) + Cure Beauty (Blue) = Purple. Cure Sunny (Red/Orange) + Cure Peace (Yellow) = Amber/Gold.

Candy is the sealed Queen of Märchenland.

 * Hence why she knows exactly who the Precure are when they transform and their powers and her knowledge about the Cure Decor. Like a similar situation to Kerberos from Cardcaptor Sakura, Candy is in a "little" form and her true form as the Queen can only be released by gathering the Decor, the pieces of her power.

Wolfrun is in fact the Big Bad Wolf, as opposed to just an analogue.
Similarly, Majorina is the Wicked Witch from the Snow White story (which is further supported in episode 5) and Akaoni is one of the onis from the story of Momotaro. Their names are merely codenames.

Candy is the daughter of the sealed Queen of Märchenland.
Which would make her a princess and the reason why she was specifcally sent to earth in order to find the cures.It could be a reason why she knows so much about Cure Decor because who wouldn't know a lot about their mother.
 * Then I suppose this would make her older brother Pop a prince and possibly the rightful heir to the throne.
 * Unless, of course, Marchenland is a matriarchal society. Which would make Candy the heir in this case.

There will not be any new Cures joining the main five...
...and all supposed hints otherwise are just Toei being Trolls again.

The Bad Ending is the Endofthe World As We Know It.
It's the reason why people lose hope when the enemy attacks, because there's nothing they can do to stop it and they give up.

The two potential Sixth Ranger Cures will start out Brainwashed and Crazy before being purified by the team.
Similar to what has happened with the Quirky Miniboss Squads from Heartcatch and Suite, blended with Cure Passion and Cure Beat's introductions in Fresh and Suite.

Every Pretty Cure will play Cure Peace's Jan-Ken-Pon game in Pretty Cure All Stars New Stage
Someone will. You just know it.
 * CONFIRMED

There will be an appearance of a Mitaro Hoshizora later on.
And suddenly Akane's joke would make a lot more sense. Though maybe he would be a distant cousin of Miyuki's rather than her brother.

The upgraded forms/attacks will only be available after enough spirit is put into the Smile Pact.
What with the emphasis on putting spirit/energy into the pact, it makes sense that it's storing it for more power later.

Miyuki was lying about having a crush on Peter Pan.
She only said that so the other Cures would quit bugging her about the subject matter. In reality, she's more interested in friendship than romance.

Wolfrun has a Dark and Troubled Past
Let's look at the archetypical Big Bad Wolf.


 * The Big Bad Wolf is always alone. He has no pack. Wolf packs are not motley crews of unrelated individuals, they're families consisting of a breeding pair and their children. We think of the "lone wolf" as a cool individual whose isolation is voluntary. But in reality, lone wolves are alone because either their pack is dead or because the pack was so antagonistic towards the wolf that it decided that going it alone and risking starvation was better.
 * TL;DR: The Big Bad Wolf's family is either dead, or was so abusive that he ran away.
 * The Big Bad Wolf does not hunt normally. He cannot hunt normally, because wolves hunt in packs, and The Big Bad Wolf has no pack. Without his pack to help him down large prey, he had to hunt smaller prey. But smaller prey is also quicker and harder to catch, and even if the hunt is successful, the meat from a rabbit is barely worth the energy sunk into chasing it. Combine this with the fact that not every day is going to end with a successful hunt, and The Big Bad Wolf will quickly start starving. In this case, the only reliable, plentiful source of food is human livestock. This will quickly draw the ire of humans.
 * TL;DR: The only reason The Big Bad Wolf comes into conflict with humans is because he's starving to death.
 * The Big Bad Wolf eats humans. Wolves only prey on humans when they're very desperate and hungry. Maybe The Big Bad Wolf got injured by a human on a failed livestock raid, and now he cannot chase even his normal prey. Humans, though, have no fangs or claws, and cannot run very fast. If The Big Bad Wolf can get an unarmed human alone, they're easy prey. This is also highly risky, since if he kills even one human, the nearest human settlement will burn the forest down just to get vengeance. He would not try to eat humans unless he was at the end of his rope.
 * TL;DR: The Big Bad Wolf has done bad things because he desperately wants to live.
 * The Big Bad Wolf never wins. With the exception of "The Boy Who Cried Wolf", all fairy tales starring The Big Bad Wolf end with the wolf losing. Details vary (run away in humiliation; get drowned in a river, get your stomach cut open and filled with rocks), but it's always a Downer Ending for the wolf.
 * TL;DR: Wolves don't get happy endings, because "happy ending for wolves" and "happy ending for everyone else" are mutually exclusive.

TL;DR: There's a high possibility that Wolfrun had a tremendously crappy life, and his bad attitude is due to him having crossed the Despair Event Horizon a looong time ago.

Pierrot will be a Disc One Final Boss.

 * Considering he'll probably debut around episode 22, and Pretty Cure averages 49 episodes, there will most likely be another story arc and villain.
 * If this happens, then we might go the way of the original series.

Cure Echo will show up in the series proper either as one of the two we've been teased about or an 8th ranger.

 * Because Echo used the Smile system to henshin in the movie.
