If say Magneto and Xavier work out their differences by the end of FC 3, then the entire OT can be retconned with a brand new threat, like Sinister and Apocalypse. And you can build off the cast of actors now in their primes, as opposed to throwing them out the window.
Patrick will keep coming back for more, I doubt he will retire any time soon
I think we could get another 3 more films before Stewart stops
