It’ll most likely depend on whatever the current trends are at the time. It wasn’t a big thing to “reboot” franchises in 1995, which is probably the only reason that GE isn’t an official reboot, although I’ve always felt that it kind of lies in its own frame of reference outside of the films from Connery through Dalton.
The next Bond, I’m sure, will be a reboot, since Craig’s tenure is most likely going to be entirely self-contained, but whatever takes hold as being popular in a post-Covid world will dictate what direction EON goes. Hopefully that means less Bond/M trust issues and something that leans more towards just allowing the professional do his work, but we’ll see.
