I don't think it's as black and white as what some of you think it might be. I think there's every possibility that we get something along the lines of a reboot, but still have the same actors playing the role. My prediction is after JL WB will essentially move on from the Snyder movies and stick to keeping the characters apart from one and other, locked away in their own little corner in the DCEU where there's no interaction with each other moving forward. Give directors like Matt Reeve, James Wan and, should he sign on, Matthew Vaughn free reign to take control of each characters part of the DCEU and let them do their own thing without having to worry about continuity, or cross overs, or whatever. Still call it the DCEU, still have the same actors, but just let them all do their own thing. Essentially, it's the best of both worlds, it's a reboot that simply ignores what happened in the Zack Snyder movies. Or, if you want a comparison, something along the lines of the first 3 Mad Max movies where the actor is the same but each story is its own thing that pays no attention to what came before.
