While HBO has not confirmed anything about the Season 8 air date, Sophie Turner's reference is likely to be the truth.
When talking about her schedule over the next year, Turner said, "Yeah, I'm really excited". While discussing her future projects of Dark Phoenix and Girl Who Fell From the Sky, Turner slipped in that Game of Thrones would premiere in 2019, a fact that HBO has not officially confirmed yet. Then I have some independent movies to be released.
"We started in October, so we're maybe like a tenth of the way through", she added, "we've got six or seven months left".
While fans are still finding it hard to come to terms with the fact that season eight will be the last for GoT, the cast too are still coming to grips with it.
She said, "It's going to be tricky for her, because at the end of last season, she felt that she had everything set up". She had her family back together. And without Littlefinger, it's a test for her of whether she can get through it ... On the eighth season working a huge number of people to make the final of the Saga is incredibly spectacular and epic.
She also said how nearly the whole cast was present during the season 8 read-through and it turned really emotional for all of them. On the question of whether the problem she will face will be the White Walkers or a political fight; the actress asked the fans to wait and watch.
Teasing the end, the Sansa actress continued, "Every single cast member was pretty much there". We all feel that we are coming to an end.
The final season of Game of Thrones will feature six near feature length episodes with budgets of upwards of $15 million per piece. Then we try to profit, to be together more, to go to the table together more often ...
