"The next one is set in the '90s," Kinberg told ComingSoon.
This follows a pattern established ever since Fox turned back the clock on the franchise in X-Men: First Class, which was set in the 1960s, the decade of the X-Men's comic book debut. X-Men: Days of Future Past followed approximately 10 years later, in universe, taking place during the 1970s. X-Men: Apocalypse makes a similar jump, taking place in the 1980s.
Kinberg wasn't entirely clear what he meant by "the next one." It could be referencing the next core X-Men movie, or it could be referencing the upcoming spinoff New Mutants movie.
The 1990s was an era of highs and lows for the X-Men comics. Jim Lee's character designs remain some of the most iconic and memorable versions of the character, largely due to their use in X-Men: The Animated Series, which introduced Marvel's mutants to a legion of Saturday morning cartoon viewers. The team also grew into two separate rosters, the Blue Team and the Gold Team, with the Blue Team in particular becoming the definitive lineup for many fans.
On the other hand, longtime X-Men scribe Chris Claremont left the series after 17 years, and the franchise became a mess of continuity retcons and impenetrable crossovers. Of course many of those crossovers could make for some spectacular blockbuster movie fodder.
