Age of Ultron was on the tv today and I heard the word "endgame" used
Tony is justifying his creation of Ultron by recounting when aliens attack through a hole in the sky, or something like that, and describes it as the endgame. Cap is emphasizing they must stick together and Tony says they will lose. Cap responds they will "do that too"
Might be nothing, but the use of the word jumped out to me since it's been made important by Strange. Could mean the Avengers will need to come together in some way and "lose" together in order to save the day. Seems pretty in line with the rumor mill. Now that I'm thinking of it, maybe I've heard this thrown around and it isn't even an original thought. Ok good talk then...
