Transformers 2, Star Trek and Gi-Joe Super bowl trailers

Paramount made my day with the Transformers 2 - Revenge of the fallen trailer. Anxious Transformers fans like me have been waiting for it since years. Can't figure out who is the robot at the end, the damn thing is so big that it dwarfs Optimus Prime. Included after the jump is 30 second goodness of Star Trek and G.I. Joe: Rise of Cobra.
