A bit late posting this, but they seem to be playing Crimson Dynamo, Justin Hammer, and Black Widow, respectively. Though there is some confusion between Variety and The Hollywood Reporter about whether or not Rourke is playing Crimson Dynamo or Whiplash. Though I think its more likely that he's Dynamo. Rourke and Rockwell are the Iron Man 2 Villains! - Superhero Hype! Emily Blunt to Star in Iron Man 2? - Superhero Hype!
