they could be 3 possibility in my opinion, first THE FALLEN himself second MEGATRON return from the death but none talk about this possibility, an AUTOBOT guy named JAZZ! maybe he will get a bigger part than we expect,remember on hasbro web site this week :TRANSFORMERS: REVENGE OF THE FALLEN began shooting on June 2nd in Bethlehem, PA. While details of the movie’s plot a closely-guarded secret, expect a key character from the first movie to make a dramatic comeback and attempt to settle a score. a key character from the 1st movie! so i'll go with jazz!
