George R.R. Martin has written 1,100 pages of new Game of Thrones book, the same number as last year

The author's latest update on The Winds of Winter will probably frustrate fans.

And with the release of the upcoming book already having been struck by several delays, the author's latest update on its progress suggests fans still have a long wait in store for its publication.

Appearing on the podcast Bangcast this month alongside fellow author Bernard Cornwell (The Last Kingdom series), Martin had the following to say about The Winds of Winter:

George R.R. Martin has written 1,100 pages of new Game of Thrones novel - the same amount as last year

Martin's comments suggest he has not made a significant amount of progress on the novel in around a year.

Appearing on Tooning Out the News last December, Martin was asked how many pages of The Winds of Winter he had written, to which he replied: "Like 1,100, 1,200 - something like that. It's not done yet though. I need another 400, 500."

In more positive news for Game of Thrones fans though, Martin said on Bangcast that around eight spin-off TV shows from the hit HBO series are in development.

He said: "Of course, in television, we have the new show House of the Dragon, which has just finished a filming a second season and we're going to be doing planning for a third season soon.

"But I also have like eight other spin-off shows that we're developing. The Dunk and Egg show has been green-lit. The others, not yet but we're still working on them, developing."
