yeah, who can say what will happen in the next whole year.
When Rachel was mentioned on the original all "cast" cover she was listed as Dark Phoenix, and there was that one variant that was done that showed her as Dark Phoenix. Someone posted that Hickman said that the poster is significant and that we will see some of the people on that poster at various points in Dawn of X. I am not sure if that means adult Cable is going to return at some point, I hope so actually.
I am on the fence about revisiting the Dark Phoenix saga, but it would be nice to have Jean free of it and trying to save Rachel before Rachel loses herself in the Phoenix force.
