Business-wise, its not a good idea to reboot this series especially the interest for X-Men movies are starting to rise up again. Its also easier to just make a sequel from an established franchise than to start from scratch.
Of course its easy for fan-boys to suggest that a reboot should happen because they want things to be more similar to the comic-books, but seriously, if you are a producer of this series and you still have most of the cast/crew willing to return and the general audience wants to see more films. You are gonna think twice about doing a reboot.
