9. War Machine
It's common knowledge that Don Cheadle's Colonel Rhodes will make a cameo appearance in Avengers: Age Of Ultron (he was featured in the trailer partying with them), but could War Machine also make a return? That's the way it looks, thanks to a number of toys featuring a slightly redesigned version of the suit he wore in Iron Man 2. (This likely means that he's ditched the Iron Patriot suit he had in Iron Man 3, which isn't really a huge loss.) It's hard to imagine Marvel pushing War Machine toys if the character doesn't have some sort of role in the movie. Ultimately, it probably won't amount to much more than a cameo possibly at the start or end of the movie, though it's been rumoured that War Machine will be part of the new Avengers team Captain America assembles at the end of this sequel, too.
