Autobots: Arcee would be sweet, but I'll leave it to Animated. Remold-wise they've got a lot of leeway - Inferno into Grapple (though Cybertron Mudflap would also be good), Sideswipe into Red Alert, Brawn into Outback, and Cheetor into Tigatron. Since we're getting a Rhinox I'd like to see a transmetal Rattrap as well, ideally Scout class.

For the Decepticons, Scourge would be nice, and so would a redone Shockwave. Would love a Dead End, he's one of my favourite characters (if they did do a new Jazz mold it wouldn't be too hard to remold it into a pretty good Dead End IMO). I'd really like to see a triple-combining Reflector as well.
