Spidey didn't make a cameo in the Avengers. Despite rumors. But the actor says he wants to be in Avengers 2.

James Badge Dale as Iron Patriot is confirmed. The photos show him. It would be interesting if Sony gives the rights back so Spidey could be in the lineup. But then would we be faced with another reboot?

Mandarin ... I hope not. It would be just a bad move. He's such a campy villain.

Firepower.. We could claim he was shown in Ironman 2. So I could see him. Firepower was part of the Gov. attempt to create their own power-suit.
