Time to get psyched.
Michael Bay has posted two and a half minutes of Revenge of the Fallen goodness. The actual video is what was shown at ShoWest 2009 and features a touching scene between Bumblebee and Sam, and then a bunch of robot-on-robot fighting.
Also seen is the first footage of Devastator in action.
What are you waiting for?
EDIT: Screen Caps added to this story, read on to see.
