Ironman 3 (Extremis)

I don't think the suit that wakes Pepper Potts is jacked. I think it's War Machine. Of course even a friendly one of those would scare the **** out of you, especially if you're curled up next to the OG Ironman.
It definitely looks like the new armor, though. Considering Tony mentions nightmares and fears of not being able to protect Pepper, I'm guessing it's a dream sequence.

For anyone wondering about the red/white/blue armor, it's been pretty much confirmed as a War Machine redesign. The design comes from the Iron Patriot armor used by Norman Osborne/Green Goblin when he tricked his way into being in charge of a new version of S.H.I.E.L.D. called H.A.M.M.E.R., and there's no chance it's him. There were some early set pics of the armor with a guy inside that looked like James Badge Dale who plays Eric Slavin/Coldblood, but it was confirmed as a stuntman and Dale was filming another movie at the time.

The real head-scratcher is Mandarin's tattoo:



It's Captain America's shield with an anarchist 'A' symbol in the center instead of the star. I suspect this version of Mandarin will have past ties to SHIELD and/or the Super Soldier Program.
