Now, with a sequel confirmed, here are my hopes and wishes:
1) The Dinobots are introduced.
2) The Constructicons are introduced and Devastator appears during the climax...

3) Soundwave joins the cast of Decepticons and Wheeljack joins the cast of Autobots.
4) Shockwave becomes the main villain of Transformers 2.
Yes. I do not want to see Megatron return in the sequel (as himself, or Galvatron, save that for the third film). Allow Shockwave to take charge of things... Give us something new, something we haven't seen before.
I'm seen Megatron too much in the last while...

Well, how does everyone else feel?
