It's hard to believe, but the end of House of the Dragon season 3 is upon us. House of the Dragon isn't the only Game of Thrones project to make a splash this year, though. Here are all 4 currently confirmed spinoff works of Game of Thrones, including a few that you can watch already. If I were a betting man, I'd expect to see it in 2029, pushed as the next new Game of Thrones spinoff after House of the Dragon ends. The House of the Dragon season 3 finale premieres Sunday, August 9 at 9:00 p.m.
