IGN:
Should Earth's Mightiest Heroes return for a big screen sequel, expect to see a different team roster.

While promoting next summer's The Avengers at New York Comic-Con, the film's producer and Marvel Studios president Kevin Feige revealed to IGN that -- just as it has in 50-plus years of comic book continuity -- the superhero team's lineup would most likely change for a big screen sequel.
