Cin­e­mat­i­cal are report­ing that, in an inter­view with Howard Stern, Jon Favreau said he had not yet be con­firmed for the Iron man sequel:

“They haven’t offered me any­thing yet. They’re all talk­ing — they want to do it, they even announced a date.”

Whilst Slash Film have run an arti­cle con­cern­ing Tony Stark him­self, Robert Downey Jr. It is thought that most cast are con­tracted for up to two sequels, how­ever when Enter­tain­ment weekly quizzed Downey Jr. con­cern­ing Iron man 2, he replied,

“I really don’t know. What I’m on board for right now is the ride home. I don’t want to start talk­ing out of my league, because that would have cer­tainly been my incli­na­tion in the past. I kind of know how to keep my teeth together a lit­tle bet­ter than I used to.”

I wouldn’t be too dis­heart­ened, these are early days and sequel talks are only just beginning.
