I should probably find out if Michael Bay is still using
Tidal Wave in this movie... I think that would go a wee bit overboard. Last I heard, Soundwave is definately in it and they were thinking about Shockwave and the Constructicons... which would be a problem since Bonecrusher is a Constructicon and he died in the first movie (the one who got his head ripped off by Optimus Prime).
EDIT: It's officially being called
Transformers 2: Revenge of the Fallen.
