How about not focusing on Prof.X? do we really need 5 movies focusing on him?
This is a good point. Let the students move on. X1 and X2, with the Xmen all being adults, didn't require Prof X really.
Noone has said how much involvement Mckellen and Stewart will have with the new movie. Before you get your panties all bunched up and stuff, you should wait on that. They might only have small parts.
Having the story shift to what Cyclops and Wolverine dynamic, it's far more interesting.
I get depressed when I think of how great this would be and at the same time, know it will never happen.
