The next X-Men film will likely not follow the storyline exactly but it could be an exciting way to reboot the entire film franchise but like Spock created a new timeline in JJ Abrams Star Trek.
I wasn't a big fan of X-Men: First Class, mostly because of the way they haphazardly played with continuity, especially when the story could have been accomplished without making such blatant changes that non-comic book fans wouldn't have blinked an eye at. That aside, the acting was probably some of the best a comic book movie has seen.
