There’s a person on Twitter who guys by the name Roger Wardell. No one’s sure exactly who he is, but he always has credible inside information on what’s going on with Marvel movies. In the past he’s hinted at Dr. Strange having a cameo in “Thor: The Dark World,” and just yesterday Wardell tweeted this:
Inside News: When Stephanie Szostak’s role is for Iron Man 3 is announced, fans will go crazy.

Which leads me to believe Szostak will be playing the heroine known as the Wasp. Although there are a number of villains she should play (most notably Madame Masque), I just have a feeling Marvel would rather have a second female hero to go alongside Black Widow than have another villain for Iron Man and/or the Avengers to deal with.
