Biggest question Is on Time travel do future character or characters go back to 1973 or will It be mind switch like original comic storyline.
I don't think it will be a mindswitch. There are limited options for characters in both timelines - Xavier, Magneto, Wolverine (except his past version may be absent), Mystique (but Rebecca hasn't been cast).
I wouldn't want to see McAvoy's Xavier have his mind overwritten by Stewart's Xavier. That stops the McAvoy version going on any sort of journey (character arc).
