Xavier's body-switch is a bit crazy (and unethical) to explain (it just sounds stupid), even if a body-switch did happen in the comics.
And will people accept the return of the Phoenix, even if fans want it and even if a Phoenix is destined to be reborn according to mythology.
I'm betting that this film will borrow elements from X-Men TAS episodes "One Man's Worth". The time traveler from the apocalyptic future will travel to the "present" (Between X2 and X3) to recruit the X-Men to their cause.
I'd also like to see Rachel Summers as the time traveler. I think it would create a lot of speculation as how she came to exist. At the climax of the film the phoenix force can emerge and the X-Men wonder how to handle the threat..
