If you're jonesing for books in the vein of ASoIaF, try Tad Williams' Osten Ard novels, particularly the trilogy Memory, Sorrow, and Thorn. They're so good that George R.R. Martin shamelessly stole several plot points and a couple characters from them.

Those books are not getting released. 6th one is in the works for over a decade, and he doesn't know how to finish them.

Would bet my life on winds getting released. Unless he has the plot of Dream already basically figured out and has been working on it alongside there is zero chance for it. Maybe some dunk stories make it

I would not bet old shoes Martin finishes even winds of winter
