*One of the new Marvel series being developed for the new Disney + streaming service will be based on the "What If" comic series
*The animated anthology series will explore how events in the Marvel Cinematic Universe could have happened if key moments had not occurred.
*Some examples could include episodes focusing on "What if Loki had found Mjolnir instead?" or "What if Captain America had not vanished during WW II?"
*More info about the series could be announced at Disney events in early April, or at Comic Con (or D23, I guess)
Maybe this is what the Russos meant when they said Cevans wasn't done with Cap after Endgame?
