In response to a question by "RealIrOnMaN," Kevin Feige revealed that Tony Stark will be wearing brand new armor for his turn in The Avengers:
"Hey RealIrOnMaN, you know what, the best part about making an Iron Man movie is deciding which of his many armors to debut. Joss would kill me if I gave anything away, but I will say that the evolution you saw his armor take in IM2 will continue in The Avengers."
Kevin Feige also said that Adolfo may have a cameo in The Avengers. He then responded to a question from "TT" about whether Samuel L. Jackson will appear in the World War II based storyline of Captain America: The First Avenger:
"TT, we're keeping Nick Fury as portrayed by the great Sam Jackson just in the modern era for now."
Also regarding Captain America: The First Avenger, Kevin Feige revealed that while there will be no Invaders in the movie, there will be appearances by the Howling Commandos. Moving on to Thor, Kevin Feige talked about why they abandoned the Old English dialect:
"Hey Jason, as much as I love Stan the man's Shakespearean dialect, we felt it would be over-bearing. However, our director Kenneth Branagh has a great ear for the English language and I think you'll find that the Asgardian speak is appropriately regal."
He also said that after The Avengers and Iron Man 3, Runaways and Ant-Man may be next in line:
"Those 4 films are gonna take up the next three years of my life! but don't worry, we're always working on more."
Kevin Feige also said there was the possibility of a new movie in The Punisher franchise:
"Punisher's back in house, and various plans are in the works."
