Not sure i probably would do Jack Kirby X-men were i in charge, or Chris Claremont.

Maybe First Class is the fresh take the series needs.

With Bryan Singer in the fold as an producer, and Shuler Donner hinting at an X-4 with the possible return of Patrick Stewart, and a sequel as well X-5.

I think they should really do a new series of films branched off from first class and just leave the trilogy alone, as much as i miss a singer wrap up it never happened and now won't properly unless he goes back and reshoots x-3 entirely.

They tried to get Singer to direct First Class and they are trying to sign him for X-4, i am sure they also have to re-sign all the other stars from the previous films except for Famke Jansen and the dude who played Cyclops forget his name. Xavier's consciousness merged with his twin brothers dormant body.

If X-4 happens i think we are led to believe or assume the deleted scene of Xavier's return and the slight hint when Magneto is playing chess at the end of X-3 that his powers are returning and are a part of the continuity.

Personally i think doing more sequels is a bad idea, but its all about the brand and they are going to milk it dry. Though i was and am looking forward to the second Wolverine picture if they can find as good a director as they lost for part II, the guy who did part one obviously is not a choice because that sucked, though i liked it on DVD enough, but the lack of the Claremont/Miller Wolverine tales was felt by most fans.
