I never got to ask a question during the Q&A. But i sliped in a quick one during the book signings. I asked about the unmarked island near the Dorne. His answer was that it was just one of the stepstones and he hadn't even come up with an actual name for it. And it didn't have a lord as of yet. And apparently there are several more islands of simalar size that are extend further east. So now i'm not even sure it is part of westeros.
I also wanted the words for house Blackwood in my LEGENDS II. To that he said he had thought up some but he didn't know them from memery. So he just wrote "Winter is Comming" which doesn't really suit the book but i wasn't quick enough to suggest "fire and blood"
