I haven't bought any of the X-men series for years now. If they bring Jean back, I will retroactively seek out any of the stories that directly contributed to her return. Until then, Marvel won't get my comic book money. It will continue to get my movie money though, as I think many of the Avengers-related films have been quite good. I really enjoyed both Iron Man movies as well as the Captain America one.

I also will continue spending money on Jean Grey items... statues and the like. Money talks.
