It looks like they're going for the version of the Ultron story I'm hoping to see.
Stark (instead of Pym) creates a robot named Ultron to save the world. Ultron decides that the only way to bring peace is to get rid of the thing that keeps ending the peace: humans. Ultron is flawed because he's more human than he wants to admit, and like his own creator, he creates his own downfall via hubris when he creates Vision.
I can hardly wait!
