Considering how popular the show was at its peak, the fact that there is still more content to come and how IPs are being rehashed all the time, it would a non zero chance that they redo the entire thing someday.
what's funny is that, from what i recall hearing, the creative forces behind the tv show essentially got bored with the show and crammed a ton of stuff into season 8 and kinda just phoned it in. iirc hbo was willing for one or two more seasons after 8
that's an insane amount of money if it's accurate. wonder why they couldn't just negotiate with hbo to let them free and have someone else do their part.
