Well wolverine, jean Grey, Xavier and Cyclops (all 616 versions) are all dead and gone. They'll do what they did with Fantastic Four, scatter them all around the Marvel Universe, but no FF book (Thing is a Guardian and Torch is in Inhumans). I imagine the X-Characters will further be scattered into Inhumans (Beast is there), Guardians (Kitty is there), and Avengers (Rogue, Cable, Deadpool and many New Mutants are on various teams). They'll simply dissolve the X-Franchise, scatter the characters so Fox can't mine storylines for Movies. The problem with that approach, Marvel hasn't made a good X-Story in years. The Gold Mine for movies is the Claremont run, and Fox can mine that forever.
