If you read the title, then yes, it is confirmed that Lt. Col. James Rhodes, aka War Machine is coming to 'Avengers: Age of Ultron'!
As of today's recent TV spot for the movie, War Machine is no longer Iron Patriot and revives his previous moniker. Though, I don't know why everybody in 'Iron Man 3' didn't like the name. The name was catchy, it fit the color scheme, and, as Rhodey would have said it, it doesn't scare everybody when he's really trying to protect them. Here's the video courtesy of JoBlo Movie Trailers:
Awesome! Awesome! Awesome! Now that should be enough people to fit the bill against Ultron and his sentries.
Anyway, only two weeks remain on the countdown for the premiere of 'Avengers: Age of Ultron'. Be sure to get your tickets now at Fandango.com (figured I'd advertise that now before it was too late).
