Jean killed herself before DP took over and she is still dead. This young Jean had not done any of that. All she's done is use her powers like any teen with powers would esp a passionate girl. I do find myself tuning in every issue to see what Jean gets up too.
Phoenix Endsong starring Jean sold pretty well (in the top 5) and the first two issues sold out. They tried to repeat the success with Phoenix Warsong that didn't included Jean and it flopped. Hope Summers had Generation Hope which was canceled due to low sales.
Not sure what Bendis or Marvel has plan for the long run. Furry Beast believes he doesn't have much time left so he feels he has to do something drastic for mutants to have a better future. Present Cyclops will see who he use to be and maybe change his ways and the original 5 x-men will see what the present holds and try to change their future. Not sure why the original 5 x-men stay though. Time travel leaves a lot of questions.
