In an interview with SFX, the writers of the Cap sequel say he’ll still be Steve Rogers in the movie:
Weâ€™ve just heard that the Falcon is taking over Capâ€™s role in the comic books. Do you think the movies can accommodate these kind of shake-ups or do they need to stay faithful to the big, familiar icons?
SM: We tend to stay on the sidelines when it comes to the comics. We wait and see what weâ€™ll steal from in three or four years from now! [laughs].
CM: I think the movies can accommodate almost anything, if thereâ€™s a need. I think there is a much greater need to shake things up in the comics because thatâ€™s a narrative thatâ€™s been going on for 60 or 70 years, so youâ€™re going to wind up having to do things to it. Ours has only been off the ground for five or so. So itâ€™s not quite time to start changing things up yet. Plus I canâ€™t figure out how heâ€™s going to have the wings and the shield at the same time. Isnâ€™t it going to get all crammed up on the wing? I donâ€™t knowâ€¦ When those things happen in the comics you also have a tendency, perhaps cynically, to go â€œYeah, but heâ€™s going to be Steve Rogers in two monthsâ€¦â€ Heâ€™s going to wake up out of cryo-stasis or whatever it is and itâ€™s going to be like â€œOh, I need the shield backâ€. [laughs].
SM: Weâ€™re all so cynical.
This means you could probably expect Steve Rogers to return as Cap in the comics, with a fresh #1 issue, sometime before May 2016.
