Keaton will be treated as A-level canon. Should already be doing it since the only actor that played it more than once and the original. The neon movies are now a branching alternate timeline i guess. The Muschiettis claim that everything filmed still exists and they won't "forget" anything, not sure if they're going to distribute official terms or designations during their marketing campaign. at&t seem to be pushing the whole Multiverse thing pretty hard. Does that mean Clooney and Kilmer are now in different worlds to explain why they look different? I don't know.
