That's an interesting take. Hopefully they'll explain why each takes their position. I could see Ultimate Carol Danvers take on that role, but I'm not sure about 616. 616 Tony, on the other hand, I could see doing that, but, hey, maybe he learned from his mistakes. Good for him to not be the villain this time.
It also helps explain why Bendis is leading the charge on this one.
ETA: Have we heard much about Carol Danvers's new comic? This might show that it has a fairly leading role in the Marvel events. On the other hand, she's in the Ultimates, so maybe that's just where it's going to be.
