Game of Thrones author George R.R. Martin has shared an update on the progress of the five spin-off shows set in the world of Westeros. With the seventh season of the hit fantasy/drama nearing closer, fans are starting to look beyond the series that took the world by storm at what’s next for the franchise – which will be prequels and spin-offs set in the vast history that Martin has created for the A Song of Ice and Fire universe.

As the definitive end of Game of Thrones gets closer – the final season/season 8 will be airing in either 2018 or 2019 depending on showrunners David Benioff and D.B. Weiss’ writing and production schedule – it was announced in May that four spin-offs were in development, with writers Max Borenstein (Kong: Skull Island), Jane Goldman (Kingsman: The Golden Circle), Brian Helgeland (Legend) and Carly Wray (Mad Men, The Leftovers) working on projects. It was later announced by Martin himself that a fifth Game of Thrones spin-off with a unannounced writer was also in the works.

Now, with only three weeks until Game of Thrones season 7 premieres, Martin has provided an update on the progress of these spin-offs and other projects in the work on his site, titled Not A Blog. Here is what Martin wrote:

“The five successor shows are moving forward at various rates of speed and there are a couple other TV projects that I can’t tell you about … how much of this will come to pass, nobody knows. Ah, the joys of development …”
