Anybody is overlooking the importance of "The New Mutants" in the X-Men continuity. We got a 34 years old Roberto da Costa/Sunspot (Adan Canto) in year 2023 (DOFP). This means that Sunspot will be 18 years old in the mid-2000s or late-2000s. Besides, we also know that Illyana/Magik is the little sister of Colossus, and we already got an adult Piotr/Colossus in 1999/2000. So "The New Mutants" is placed in the 2000s, I would say 2008 or so. If there are NO reference to the mutant race going gradually "extinct" or the lack of mutant births since 2004, we can safely assume that "Logan" is an alternate continuity. Hopefully. "The New Mutants" could be the final milestone in the continuity and the key to understand the fate of the revised timeline better.
