Disturbed will eventually invite Fuzz to rejoin while keeping Moyer
Disturbed pulling an Iron Maiden (Adrian Smith and Janick Gers) because, why not? I've heard that one of Fuzz's reasons for leaving (aside from being kicked out) was to take care of his family. This could be plausible in a few years once his kids have grown up, or if he - like the other band members - chooses to take his family on the road with him (though some of it had to do with his loosing interest in the rockstar lifestyle). I've always thought his style was more in tune with a guitarist than a bassist (he started on guitar and later moved to bass). He could take up rhythm guitar for an alternative (Donegan layers several tracks with rhythm guitar). There was also an old video somewhere on the internet of him playing in a Disturbed cover band in Chicago called Indestructible, so he's at least in practice and still follows the band's work. I'm not sure about bad blood between them; Draiman says that they sometimes keep in touch, but in a recent interview, Wengren when Fuzz was referred to refused to even mention him by name ("Our previous bass player"). There was also a Facebook page of Fuzz "setting things straight" in a short essay, but I've never found out if it's real or not.
David will sing guest vocals on a future Art of Dying release
AOD made a blog post a while back claiming that their new album Vices & Virtues had at least two guest singers ("Can you guess who they are?") with one of them being Adam Gontier. They recorded this album in L.A. roughly around the time when David was on his break, having just finished the Indestructible tour: the final date of that tour was July 3, 2009 while the band entered the studio in February 2010 to begin recording Asylum; AOD got signed to Intoxication records in December 2009 and made the post two months later on Jan 27 of the next year, just before David would head to Chicago to work on Asylum. By that time he'd have been well-rested with nothing better to do, and he owns a house in L.A. David and Dan are really trying to help this band into the mainstream. I wouldn't be surprised if David wanted to give them a push by singing on their record.
At five albums deep, they're roughly the same age as Black Album Metallica, which gives them free reign to start working on side-albums, non-album material and promotions removed from the main discography (after all, every band needs something to promote between record cycles). My guesses are:
Acoustic album/EP: That performance of Remember during MAAW IV was just the beginning (Godsmack was able to do this semi-successfully). May or may not involve the MTV Unplugged series. I'm personally rooting for a slower version of My Child or Overburdened. Disturbed was asked about this and they said they felt their songs would lend themselves well to being unplugged.
B-sides & rarities collection: Fans have been begging for this one (Hell has been out of print for years now).
Alternatively, a band member of Disturbed appearing on the album of one of these people's bands would work as well (look at the above WMG for instance).
They could either make one song (Godsmack and The Scorpion King), an entire album (ACDC and Maximum Overdrive) or Dan and Mike could score the production. I think they're capable enough song-writers by this point to try other musical forms. Even if it fails, there's still a chance it becoming a Breakaway Pop Hit. As for the prospect of doing TV, I'm looking at Sons of Anarchy (their manager spilled the beans that they're doing something with the series, but didn't specify what).
Tour-spanning 3-disc live album: They haven't done this yet (Live and Indestructible was just an EP and MAAW II was a live compilation with the other artists involved). Something at the scale of Live Shit: Binge & Purge would be nice.
Cover Album: In line with Metallica's Garage Inc., but with fewer repeated artists. Too early to make one? When asked about this, David said "Jeez, I don't even know what we would cover..."
If you want to see my personal wishlist for them to cover, open the hot tip
After retirement David will become either a motivational speaker or politician
Because I don't doubt he would succeed at that.
Semi-confirmed. He was working on his own politically-themed radio program for a while but dropped it. He says he has a few projects on the burner during the hiatus.
Disturbed will one day get caught up in a Die Hard situation
Dan will lead a successful producing career on the side
In a few more years he could probably afford his own small studio to help young, talented bands. He does know quite a bit about how to make a strong hook.
Confirmed. He's apparently been wanting to do it for a while.
↑Yes, this is the track order: Led Zeppelin: Heartbreaker/Living Loving Maid (She's Just A Woman) Black Sabbath: Symptom of the Universe Testament: More Than Meets The Eye Iron Maiden: No More Lies Dokken: Dream Warrior Soundgarden: Jesus Christ Pose Queensryche: I Don't Believe In Love Tool: Vicarious Alice in Chains: Them Bones Ratt: You Think You're Tough Sevendust: Black Motley Crue: Shout at the Devil Dio: Rainbow in the Dark Slayer: Bloodline Korn: Blind Aerosmith: Dream On
