Because there will be fewer episodes in Season 7, there was at first a hope that we might still get new episodes around the same time as usual, but as the months have worn on, it has become clearer and clearer that won’t be happening.
Sunny weather will be out in Season 7 and more grey weather will be in.
What we do know about the upcoming episodes is that production started later this TV season, thanks to the Game of Thrones team needing to shoot more scenes in winter settings.
At least the show isn’t dealing with a year plus delay, like Westworld is.
