We may have to wait a little bit longer for new episodes of 'House of the Dragon' and 'Euphoria'. The second season of the acclaimed 'Game of Thrones' prequel will air in "early summer" of 2024 and will consist of eight episodes, two less than the first. In addition, 'Euphoria' season three, 'White Lotus' season three, and the HBO's prequel series to Stephen King's novel 'IT (Welcome to Derry)' have all been pushed to 2025.
