Xavier is dying. No doubt about that in my mind. The question is..does Emma die too? The solicit for the "death one of Marvel's greatest heroes" is for A v X #12 and at the end of the Uncanny run, someone from the Extinction team is going their own way from everyone. Might be a Cyclops solo book since we don't know what's coming with books rolling out from Marvel until February next year. Magneto, Cyclops, Emma, Namor, Hope, Colossus, Magik aren't seen in any of the solicits for November. Magneto survives though because he has some kind of offer for Rogue post AvX that wraps up X-Men Legacy before the relaunch with Legion.
Magik was on a role in this shyt though..she was whooping everyone's asses. Thor, Strange, Ms. Marvel, Rogue got teleported off planet to stop her from running to everyone about the hell prisons.
