Marvel has just released some kick ass concept art that will/should be available at San Diego Comic Con 2012 for Iron Man 3! Now, from what I’m told it looks like the plot is going to have something to do with Extremis?
Now, Extremis is supposed to be a tech based virus of some sort that creates super soldiers. Correct me if I’m wrong cause my comic book lore could be off the mark. And it looks like Tony Starks arm and leg could possibly be turning into the red and gold armor.
Who knows but check out the concept art below!
