From a preview of All-New X-Men #22, the Beast lays out the current state of Marvel, specifically X-Men, continuity, that happened after the nineteen sixties (in publishing terms, they're from the early noughties in current continuity terms I guess).

I wonder if they didn't just cut and paste from the X-Men editorial whiteboard? The worrying thing is, I can follow most of it…

And could alternate timelines be the answer to bringing back the likes of Professor X?

And what would happen if the Beast just erased it all?
