I do think the Avengers need some diversity outside of Nick Fury (everyone seems to forget that a black dude put the team together). But I don't think we'll see that until Avengers 3 with Black Panther & maybe Wasp. War Machine, Falcon & whoever else will be in the movie, but I don't think they'll be actual team members or do much outside of action scenes.
Won't Avengers 3 be even more crowded? Especially as Ultron will likely effect Rhodey, I see him either cameoing or being distinctly mentioned. I don't see another comic prequel explanation for his absence.
The MCU has tons of diversity outside of the Avengers, no doubt about that. I strongly suspect we'll see Falcon in Avengers 2 in a Hawkeye-sized role.
