Guess who's gonna be in Transformers 2!

Yep, that's right. None other than Soundwave! Roberto Orci, one of the scribes of the Transformers movies, told IGN recently:

Q: Is there one particular Transformer, good or bad, that you absolutely had to get into the sequel?

ORCI: Yes.

Q: You're not gonna tell us.

ORCI: I'll tell you. We had to get Soundwave in there.

Q: Nice. Where Soundwave goes, will Ravage follow?

ORCI: Perhaps! Who's Ravage? … I'm kidding! You know, we had Ravage in an early draft of the first movie and Soundwave, and we couldn't do it right and I think this time hopefully we'll have the ability to do it.

Booo-yahh! I'll leave you with this little nugget…

Also, the interview above has a few more details on the sequel as well info on the Star Trek movie.
