Maybe by 2020?

I don't actually care about this (not a Game of Thrones fan), but George R.R. Martin nerds everywhere were chagrined to learn that he has zero chance of finishing the next installment of his best-selling series on schedule. Martin takes full responsibility for the project going off the rails, but if his long, meandering LiveJournal post on the subject is a good example of his thought/organizational process, I'd be surprised if the book comes out in the next calendar year.
