Eventually, once Secret Wars ends and Marvel reveals whatever the hell is going to be the Marvel universe going forward, a new Avengers team will need to be formed. Excuse me, an All-New, All-Different Avengers — whose roster Marvel has semi-revealed, including the new, Thor and Ms. Marvel.
I say "semi-revealed" because, well, you can see for yourself:
This is the cover of Marvel's Free Comic Book Day offering, teasing the All-New, All-Different Avengers, which assumably will be released after Secret Wars wraps up in June under the same title. The characters will obviously be revealed over time, but it speculation of course is half the fun.
I'm guessing that's new Cap/Falcon in the middle — with wings again and the shield, obviously — and that looks like Iron Man on the left. I'm going to guess the Vision is on the upper-right, given that the character is wearing a cape and Vision will be a major part of the Age of Ultron movie. As for the bottom, this looked like Spider-Man to me... until I noticed his buccaneer-style boots, which Spidey doesn't wear.
Your guesses in the comments, please! (And the next Free Comic Book Day is May 2nd, so mark your calendars.)
