It is interesting, we know exactly the role megatron now plays. But is there any reason why bay and co have kept megatron away from the trailers etc etc. We have seen all the transformers, optimus, sentinal, shockwave, soundwave, starscream. But megatron is the big mystery, why he is kept has the big secret of DOTM, or he has not been revealed to anyone. Only the game we have seen him in.
