It was based on him apparently discussing details of future books with the producers during the making of Season 1, for example, he told the producers who Jon Snow's mother is.
But as I said, it's all speculation, I personally think he will finish the series before he dies, but if he doesn't, I reckon he will want it left unfinished, and would be write to. I personally don't want to read ASOIAF by another writer.
I did not know he told them that. Huh. I honestly didn't think he'd ever reveal Snow's mother.
I see what you're saying. I'm the kinda guy, however, who likes to hope for the best, and plan for the worst. If I were him, I'd want to make sure the fans who had devoted that much time to enjoying my work were given a sense of closure, so I'd go the Jordan route, and make sure someone could finish my work. You disagree, and I respect that, and we'll have to agree to disagree.
But again, depending on the wording of his contracts, what he wants and what will happen could be two different things. If the publishers thought to make sure they had a right listed in the contract to finish it should the worst happen, they'll finish it without him if need be. Especially seeing as how it didn't hurt the WoT sales when that happened at all, so they know the MONEY would be there.
