Dead characters aren’t simply going to be rebooted in the future of the Marvel Cinematic Universe in the wake of Avengers: Endgame, according to co-writer Christopher Markus.
How exactly that’s going to be possible remains to be seen, but it would keep intact the notion that, in the MCU present, Vision is dead.
There are alternate versions of Iron Man from the comics and other spins on many of the MCU’s biggest characters.
