I think, like people have said, there's a good chance of Starscream and Ironhide/Ratchet. I'd also love a Sideswipe and/or Slipstream.
Omega Supreme, mainly because even if they killed the line after he came out, he would fit in perfectly with the classics!
Realistically we're probably looking at Starscream, the inevitable seekers (I'll actually be able to collect a full line of seekers from one given line now =D), and Ironhide/Ratchet. However just based on sheer fascination with design, I think my dream wave would include Starscream, Air Raid, and then a second wave to consist of Brakedown and Sideswipe. Then from that point on I'd probably want to see the rest of the cast, if they were to do them, in this pairing/order. Barricade-Brawl (A Movie 1 tandem =D) Warpath-Jetfire Ratchet-Thundercracker Silverbolt-Skywarp Ironhide- (Is there a campaign con I'm forgetting?) The DLC characters I can't see being used, or the Fembots. Simply because none of these have a character to support. We've seen weirder, but a toy based on a digital model without anything to supplement without it just seems a tad odd. Would I like a Jazz toy though? HELL YEAH. Scattorshot and Onslaught are also top picks. Scattorshot could also be redecoed-tooled into Perceptor.
I'd love to see Zeta Prime or Slipscream, but only if Slip's transformation is like it is in the game.
The ones I want are Warpath and Slipstream. Though I also would like Brawl, for the reason of repainting him into one of my multiplayer soldiers (though I might have a kitbash idea for that, at least I hope...) I'm really not a fan of Starscream's design, so it's too bad he'll likely be next (if they continue). But it does make sense.
Ever since I got these figures Ive wanted a Starscream, so it looks like im gonna get my wish. Can't wait til Megatron and Soundwave are released so i can get my hands on them. Other than that I'd probably like to see Silverbolt or Brawl. If they released Ratchet or Ironhide I would buy it too
I would like to point out that the ratchet/ironhide designs in this game are completely independent of each other and wouldn't really be suitable repaint fodder for each other. Two new molds please.
shockwave, cause the design and altmode are awesomes and i'd like to see a barricade, he looks very cool and stunticon-ish IMO
Realistically- Skywarp and co Wish List Warpath Brawl Air Raid ... and pretty much everyone else. But mostly those 3.
Stascream (and the inevitble Skywarp and Thundercracker repaints) Slipstream Silverbolt Brawl Barricade
