It looks like things are a-changing in Fox's X-Men cinematic universe, and it could have everything to do with the mutants' biggest and baddest foe, Apocalypse. Rob Liefeld seems to be hinting that the studio's decision to do a film about the ancient villain has put other films in development in the X-universe into disarray and now X-Force, based on his comic book creation, may not even happen at all.

Liefeld answered this in response to a fan via Twitter:

Everything changed when X-Men Apocalypse was announced… RT @actionscomics: @robertliefeld and the movie of x-force? What's new? — robertliefeld (@robertliefeld) June 2, 2014

Sounds ambiguous enough, and could mean anything, but then he came back with this less positive response to someone else's speculation that the film had been "shelved" altogether due to X-Men: Apocalypse:

Could it all come down to Cable, who is integral to both X-Force and Apocalypse? Liefeld is staying mum on whether Cable being needed for Apocalypse is why X-Force is in flux:

I have no idea if Cable will appear in future X-Men films. Hard to believe he won't appear in Apocalypse but I don't expect it. — robertliefeld (@robertliefeld) June 2, 2014

But don't lose all hope just yet:

Negativity? Be patient! RT @RyanRocca: So with the negativity around x-force film being made, do you feel DP has a chance? @robertliefeld — robertliefeld (@robertliefeld) June 2, 2014
