Well, guys, put it like this, if she doesn't come back next year then they have truly decided to keep her dead long term, possibly for decades.   

I said 2013 is the last real hope we have (pun intended) because sometimes characters that have been dead for awhile come back for anniversaries.  Magik and the Red Queen returned around the time of Inferno's 25 year anniversary.  

The only other possible way Jean will be back, if not for the 2013 anniversary, is if the X-men movie franchise users her again and its a hit.  I agree with both you, quite clearly it doesn't look good for Jean's return.  At all.  But I'm someone who always keeps hope, because if you have nothing else, there's still hope.
