Well, this is surprising, although makes perfect sense considering the fact that Iron Patriot is sporting a gun on his back similar to War Machine's. According to the ever reliable folks over at
Latino Review, while that is the Iron Patriot armour in those photos from the set of
Iron Man 3, it's not James Badge Dale's Coldblood under the armour or any other villain for that matter (in the comic books, it was Norman Osborn whoe donned the suit). Instead, that was just a white stuntman filling in for Don Cheadle during filming of a scene which also involved Tony Stark and other US military types. Their source on the set tells them that while he may end up being called "Iron Patriot" in the threequel, it IS still War Machine and simply Rhodey's new armour. So, NOT a new character who we will see facing off against Iron Man. Be sure to click on the link below for more details.
