Where do you think it will go after IW? Personally, I think the MCU might leave Earth behind for a bit. After tons of space characters make prominent appearances, I think it would be a good idea to follow up with some space movies. There could be an Adam Warlock movie, Doctor Strange 2 could focus on realms, I predict a Planet Hulk movie in the far future, and something containing the Watcher. Maybe by 2030, we could get a What If? movie.
