A better question would be to ask that of the comics. With soooo many more superheroes in the comics, you'd think that more of them would be able to help out on occasions like this, right?

Anyway, we'll see. There'll be a reason why it had to just be Iron Man dealing with the Mandarin. And likewise, with Thor and whatever he's dealing with. Plus, SHIELD are busy anyway...
