I don't believe for a moment that they're going to cancel the X-Men. Not at all. Too much money there. But reboot the X-Men? Yes. I can see that possibly. And in said reboot, change them from "mutants" to "Inhuman" - I can see that happening as well. They're already doing it, as I said, in Avengers 2, in order to use Scarlet Witch and Quicksilver.
