I don’t really get why people worry about Game Of Thrones catching up to George R. R. Martin/Ice and Fire. A Storm of Swords got split into two seasons due to abundance of events and it’s 973 pages.
A Dance With Dragons is 1040 pages. Probably split into two seasons.
The Winds of Winter is supposedly going to surpass 1500. In theory, that could be three seasons. Same with A Dream of Spring. In theory, there could be up to 10 more seasons of the show. I hope there isn’t (I’d rather not watch how far they could branch away from the story in 10 years), but he isn’t going to take 10 years to finish these books.
I’m not terribly worried about it due to at this point placing more importance on the books themselves, but I am a bit annoyed that people keep talking about this. I just don’t think they aren’t going to catch up to him.
