Speaking at the Television Critics’ Association summer tour, HBO programming chief Casey Bloys noted that the decision was down to creative choices. “I think David Benioff and D.B. [Weiss] have a very specific plan about the number of seasons they want to do,” he said. “If I could get them to do more, I would take 10 seasons, but we want to take their lead with what they can do and what the best version of the show is.” He could not confirm the rumour that the final season will consist of only six episodes.
Asked about a potential spinoff, Bloys said there has been some discussion. “It’s something I’m not opposed to, but it has to make sense creatively. I’m open to it. The guys aren’t opposed to it, but there’s no concrete plans.”
