Iron Man 3(April 2013)

Extremis gave him that? I swore that in the trailer the suit coming to life was Tony trying to give his suit sentience, but instead made a crazy posessive girlfriend in the form of a suit of armor. And yes I refuse to use the term "Yandere" to describe it.

Well, they've stated that the story in 3 will involve more of the Extremis plot, whereas 1 only had the captured by terrorists part. The Extremis Armor is controlled directly through his brain. It doesn't look like they'll be using Extremis itself, but the wireless control concept. It ties in with the statement earlier where he says "And when I sleep, I have nightmares", as well as equipping the glove without any physical or visible interface.

Also, the Mandarin's rings are alien technology, not magic.
