Yeah, but that would have REALLY cheapened the movie. Having Iron Man come in and save the day in a movie called "The Incredible Hulk"?? Yeah, in an Avengers movie, maybe, or for an earlier fight. Not a final fight and not as a cameo. Thematically and dramatically BAD idea.
Also Tony was too busy being with three supermodels to help out.
