But for those who can't get enough of Westeros and its inhabitants, there are a five spin-offs in the works.
"There is no set timetable for these projects. We'll take as much or as little time as the writers need and, as with all our development, we will evaluate what we have when the scripts are in". When asked for details on the upcoming spinoffs, Bloys couldn't reveal anything concrete.
He also gave an update on the five Game of Thrones prequels which are now being worked on by HBO.
The long winter is here, and by that we mean the agonizing wait between Seasons 7 and 8 of Game of Thrones.
"What I don't want to do is detract from the final season", Bloys explained. "We want some separation there". He added that there "may be [familiar] bloodlines". Spending more than a year to make just six episodes has to be some kind of industry record, but showrunners David Benioff and Dan Weiss have always been determined to increase the series' spectacle every season and deliver a final run that satisfies even its most demanding fans. In fact, Game of Thrones was breaking its own ratings records throughout Season 7.

The Deadwood movie is also "looking very good", according to the exec, with the potential to finally begin filming sometime this year.
There has been speculation about what any new series could be about but there are a few topics which will not be making an appearance.
Game of Thrones has reached a status where it can do pretty much anything and its millions of fans will lose their collective minds.
George RR Martin, the author of the books that GoT is based on, seems to be a fan of Cogman.
He joins the other four writers: Max Borenstein, Jane Goldman, Brian Helgeland and Carly Wray. Just like with season eight, we're willing to wait, but we don't like it.
