For that reason, the 2019 eighth season wrap buys one of those prequels much-needed time - time to undergo script development, and perhaps time to get a pilot order. Since then, star Sophie Turner let slip in a recent interview that she didn't expect the show to come back until next year either. It is now logical to assume that the "GoT" prequel will arrive in 2020, which gives HBO even a little more valuable time to flesh out a new series and to promote it (not that a "GoT" spinoff will need all that much promotion). Benioff and Weiss will also write the new season along with Bryan Cogman and Dave Hill.
It is said that the series will not air in 2018 as David Benioff and Dan Weiss are working on the final episodes.
Benioff and Weiss will direct and write in the final season-sources previously told The Hollywood Reporter they'll be in charge of the series finale.
Though shooting began in October and the final season will have only six episodes, compared to 10 in the first six seasons and seven previous year, there had been indications that the fantasy epic wouldn't come back in 2018. We'd heard rumors of the shortened season order and thus, we're planning for this but to hear that its six episodes and not seven (like Season 7) is a bit disappointing. In other words, HBO had made it clear that it won't speed up production to meet a specific release window, so it's hard to make any predictions about a potential premiere date.
I guess until 2019 fans will just have to keep rewatching all the past seasons. While some episodes may be longer than usual, once again we're hearing not to expect feature-length episodes throughout the season.
Condensing the final season to six episodes means that we can, nearly without question, expect longer (perhaps feature-length?) episodes.
