Yes but hawkeye was an original Avenger and was only put in Thor as a tease because he was already going to be in the Avengers. My reason for it being Iron Patriot is because they already said months back that Ultron was created by the U.S. Government. Now everyone just speculated and said it was Shield, or Hydra, and now even saying it's the Governments response after the events of the Winter Soldier. Those could very well be true, especially the latter, but it might be more simple than that and that the U.S. Government doesn't trust Iron Patriot anymore because of his affiliation with Stark and Shield, and turns the suit into Ultron, or at least a Mark 1 Ultron.
