I initially assumed he would be playing Gateway, but with Blink that would be massively redundant. Right now I'm strongly feeling it's a radically different Bishop.
Who's to say Bishop isn't a background mutant in the future for this film that helps the surviving X-Men or something? Or a foreign mutant in one of the prison camps to show that the future is hellish all over the planet?
