I have to agree that it really does feel like the end of the X-Men we knew's storyline.
I think that this is exacerbated by the fact that the true 616's Cyclops (who isn't Young!Cyclops) merged with the Phoenix Force and was definitively killed by Doom during Secret Wars, but there's some version of that "same" Cyclops who's been apparently the source of a much worse image for Mutantkind based on how Storm's talking about him in
Extraordinary X-Men, and seems to be still alive from how Beast mentions not being friends with him in quite some time in
Inhumans.
Also - Tempest's comment to Beast at the end of UXM 600 makes me think that the terrible "Mutant Revolution" event that Hank's been fucking with all reality in attempting to stop the whole time with all his meddling (but ultimately ends up causing) might actually be the version of those events from the All-New All-Different universe.
Given all of this, I haven't decided if all this makes it worth making a new thread for the All-New All-Different continuity yet. (Also, minor
Extraordinary X-Men comment - I think that the idea of Terrigen making Mutants sick, sterile, and killing them was used as a good way to show why Humans want them dealt with, as it's using a fear of disease rather than solely prejudice based on minor differences of source of superpowers).
