If they do reboot, it'll be to remove Cavill Superman and Affleck Batman from continuity while keeping Gadot WW and Mamoa Aquaman. Keep what's popular and get rid of what isn't. Keep in mind we still don't know what is in WW '84. It COULD be a soft reboot, it might not. I always thought a Batman who was older than the rest of the League was a bad idea to begin with and making Superman a murderer his first time out is a bad idea so it wouldn't break my heart if this universe dies.
