I think I heard somewhere that Robert Downey Jr. makes a quick cameo as Ironman in the new hulk, but I don't know if that is true.
that would be cool.
with Marvel now taking over fully on all their own movies they should continue to get better and better. I'd love to see random cameos by Wolverine, any of the Fantastic Four, etc. Like a random appearance by the human torch would be sweet.
any rumors of who's going to be Captian America, or Thor? You'd figure they both have to be, blonde, blue eyes, tall and all jacked up but one has long hair.
