I wouldn't be surprised if he wanted out. That's really the only reason to kill him. You don't completely rebrand a show so that he can be the lead and then kill him off so quickly. That said, he is a very good actor, but where they've taken the character has completely ruined both him and the show.
With these writers, I wouldn't be the least bit surprised if they completely ignore the cliff hanger, have another time jump, and start out the next season with everyone back together.
