The Avengers films, ideally, in the grand plan are always big, giant linchpins. It’s like as it was in publishing, when each of the characters would go on their own adventures and then occasionally team up for a big, 12-issue mega-event. Then they would go back into their own comics, and be changed from whatever that event was. I envision the same thing occurring after this movie, because the Avengers roster is altered by the finale of this film.
