2026 will be a big year for Game of Thrones prequels, with both House of the Dragon season 3 and A Knight of the Seven Kingdoms arriving on our screens. There are still plenty of prequels in development, too, but author George R.R. Martin has revealed that there are still a few ideas for sequel series in the works.
"Apart from The Knight of the Seven Kingdoms and House of the Dragon, there are other Game of Thrones spinoff projects in development. Most are prequels," Martin told Spanish-language site Los siete reinos (AKA The Seven Kingdoms). "There are several in development, five or six series, and I'm not developing them alone, I'm working with other people. Yes, there are some sequels."
