You know, thinking about this... Couldn't this be Detroit Steel rather then Iron Patriot?
Think about it... we've already seen Justin Hammer, we know he's an enemy of Stark... and Eric Savin, is meant to be a cyborg in comic canon.. Given the Detroit Steel armor is interfaced with the spine of the wearer directly... and that the third movie features Extremis by some accounts... Wouldn't it be more logical that it could be Detroit Steel?
Also fits with the speculation of Justine Hammer making an appearence, since she was heading Hammer Industries when Detroit Steel was created... Plus... we know The Mandarin makes an appearence... and Justine Hammer did have her daughter Sasha with him in comic canon.
