After the ending of Game of Thrones back in May, fans have long hoped that the final season would get a remake. Perhaps this is a teaser for it?
A simple Tweet from the official Game of Thrones Twitter account has caused fans to put their speculation caps on. While I would certainly doubt that HBO is going to remake season 8 of Game of Thrones, some fans believe this could be a hint towards that very announcement.
It's much more likely that the Game of Thrones Twitter account is teasing fans for an announcement regarding the coming Game of Thrones prequel show -- House of the Dragon. House of the Dragon is centered around House Targaryen and will focus on the book Fire & Blood, which reveals a lot of the Targaryen's history. Another theory about the Tweet is that the Game of Thrones Twitter account is just warning everyone that Winter is actually coming in real-life. This would be a hilarious joke, but probably not the one Game of Thrones fans want to hear at the moment.
