Re: What new armors should be featured?
Avengers movie - Hulkbuster and Mark VII
Iron Man 3 - Mark VIII, Mark IX, and Mark X
Also they should hint out that in between the Avengers and part 3 he's been working on specialty suits like the deep sea suit, space suit, stealth, etc.
Maybe he wouldn't use them in the movie, but just have them in the Hall of Armors as a nod to the fans.
