I have given up on this series. I’m not even sure I would read the next book if it was released tomorrow. Maybe if the series is ever fully released I might reread it from the beginning to end. It’s like if Netflix published books.
We are 2 years away from there being more time between now and the last book being released and the time between the first and last book being released.
Here's an another uncomfortable statistic: most of ASOIAF was published before 9/11.
Personally I gave up after AFFC, which I read around a decade ago. The quality of writing had plummeted, and it was increasingly obvious the series is going to take way too long to be finished.
The guy should just give up, relive himself of the duty and the audiences of the frustration, and spend his remaining years peacefully writing Dunk and Egg stories.
I also gave up after reading AFFC about a decade ago, with the intention of picking the series back up once the next book had released.
But at this point he’d have to finish the entire series before I’d even consider going back. And I doubt he’ll ever do that. I think eventually they’ll just get someone else to finish it.
