“I suspect that you have not seen the last of Westeros on your television sets either, but I guess that all depends on how some of these successor shows turn out,” Martin wrote.
He also promises, "I'm still here, and I'm still busy."
Martin is producing five shows for HBO, Hulu, and the History Channel based not only on his writings but those of others. He’s also consulting on a video game in Japan.
But the main takeaway from his message to fans is that he is working on the final books, but it is in a different format than what Benioff and Weiss created in.
“How will it all end? I hear people asking. The same ending as the show? Different?”
“Well... yes. And no. And yes. And no. And yes. And no. And yes,” Martin wrote.
He said Benioff and Weiss had only six hours for the last season to wrap up everyone’s stories. Martin estimates he’ll have about 3,000 manuscript pages total. But if more is needed, he’ll expand it.
He also reminded fans that there are characters in his novels who didn't make it on screen.
Martin then issued his readers a challenge: "How about this? I'll write it. You read it. Then everyone can make up their own mind, and argue about it on the internet."
