Yeah, I think for the immediate time, Jean Grey won't be coming back.  We need to accept this or at least not play into their game of antagonism.

I'm even starting to doubt that Jean will be returned to us by late 2013....

...Although, Marvel and the writers have...tricked us fans before, about Jean and other topics, so maybe they do know something/have something planned, but it is still quite a ways off and they still need to get through AVX and perhaps some other major storylines before Jean's story....?
