Really strange turn of events, classic Cable is killed by a younger version of himself, Apocalypse is turning into a human, X-Man is having another Shaman moment and both Stryfe and Sinister are mysteriously absent. Something isn't right here
I like your theory psylurker! If Apocalypse finally managed to take over X-Man body that would explain why Nate has his own horsemen now. Still if that's case I would have preferred to have the classic Cable going up against an "evil" Nate controlled by Apocalypse.
A fight between Cable and X-Man is always entertaining:
Although Bishop vs X-Man could be interesting too!
