X-Men sequel finally has a title

Up until now the sequel for X-Men: First Class has been promptly referred to as X-Men: First Class 2. We now have the official title for the film along with some minor updates. The official title is X-Men: Days of Future Past, Matthew Vaughn is for sure returning to direct, and it is possible that this film will serve as somewhat of a crossover between films. X-Men and X2 director Bryan Singer suggests that it could follow the comic arc that takes the mutants into the 1980's.
