It's 2015 which means we're one more step closer to the 3 X-Men movies which are coming next year. Among them the most exciting is X-Men: Apocalypse which has a release date of May 27, 2016.
What happens to the X-Men franchise after fighting Apocalypse? As we all know that July 23, 2018 is date set for another X flick which should be a modern day story, featuring the original cast, with the new mutants introduced in X-Men: Days of Future Past. My guess is we can have Shi'ar Empire after Apocalypse.
It can help the franchise to get attract even more comic fans as it will focus more on fan favorite Scott Summer's story and background. The trio of Summers brother will be a boom for the franchise. Along this we can have Alex Summers aka Havok with his love interest Lorna Dane aka Polaris, mistress of magnetism on big screen. Also it will be an opportunity for X-Men to have a space trip and crossover is Fantastic 4.
Sony hack revealed that Fox is planing for a X-Men & Fantastic 4 crossover. If not Shi'ar Empire the mutants could team up with the Fantastic 4 along with Silver Surfer to fight planet eating Galactus, which mean more fighting stuff for the original cast.
Fantastic Four 2 is set to release in 2017 and no further information is available yet for the franchise. Merging mutants and Fantastic 4 together will give boost to both of them.
