Oh, yes, I know he can power the suits without the reactor. I should have phrased that better! I meant that it seemed as if he was moving on because that arc reactor was symbolic of his time as Iron Man. I'm glad he's free of it, though, because that must have been a pretty awful reminder of Afghanistan and his vulnerability to that shrapnel.

I expect money will talk. ;) The studio will push hard for RDJ to return because his movies are such moneymakers. If the script is good, he'll probably consider it. And I do expect to see him in The Avengers 2, even if only in a limited role.
