Who is the new Iron Man?

Matt Fraction has been hinting that there are big changes coming in his Marvel comic, Invincible Iron Man as story threads he has been working on for years all come together. In this week's Axel-In-Charge interview/column at Comic Book Resources, Fraction was talking about his various books at Marvel, including The Defenders, The Mighty Thor and Invincible Iron Man. He is also one of the writers of Avengers vs. X-Men.

Marvel took the interview as the time to debut a teaser image they created for the changes coming ahead in Invincible Iron Man.
