Just saw this over at TeamXbox and figured I should share... The writers have announced all the Transformers making an appearance in the film.
Autobots:- Optimus Prime - Bumblebee - Jazz - Ratchet - Ironhide
Decepticons:- Megatron - Starscream - Brawl - Bonecrusher - Barricade - Scorponok - Frenzy - Blackout
I'm a bit disappointed I was hoping SoundWave would be in it also... Via TeamXbox edit Because English and I don't get along. ;)
