Winter is coming…but slowly.

Game of Thrones fans were left drooling for more of the HBO hit when its sixth season wrapped but may have to wait longer than expected.

The series creators revealed on an Ultimate Fighting Championship podcast (theyre fans) that they will wait to film the next season for grim weather.

Season 7, will probably [air] a little bit later, said the shows David Benioff and D.B. Weiss on UFC Unfilitered. Because at the end of this season, Winter is here. And that means that sunny weather doesnt really serve our purposes anymore. We kind of pushed everything so we could get some grim, gray weather even in the sunnier places that we shoot.

The duo did not rule out a possible prequel after the show ends in two seasons but added they havent had time to even think about it.
