If you stay until after the credits there is an extra scene involving Samuel L. Jackson as Nick Fury that sets up either an Iron Man sequel, a Nick Fury movie, or an Avengers movie (or even all three).

I find it hard to believe that they'll do an Avengers movie for the same reason that I don't expect to ever see a Justice League movie that casts Christian Bale as Batman... too many big name actors fighting over screen time and who gets top billing.

I didn't know Robert Downey Jr. was going to be in the Hulk movie. I watched them film a bit of that down the street from where I live and saw Edward Norton and Liv Tyler. A local restaurant was set up to look like "Stanley's Pizza Parlor" (a play on Stan Lee's name). Stan Lee's cameo in Iron Man was pretty funny.
