This Q&A was nice in that it seemed we had a lot more time this time around (than when he was here for TGS). But unfortunately, I don't remember a lot what was asked.
I remember someone had brought up that Brandon had mentioned in the past that Mistborn is a trilogy of trilogies and that down the road, one of the trilogies will involve sci-fi. The person's question led to when that does happen, how does he plan to handle the allomancy in space. Brandon basically gave him a RAFO as he didn't know yet himself.
What my question was since it has been said many times that The Stormlight Archives is a planned 10 book series, I assume he has an outline of all the books already to have an idea it will be 10 books? Brandon said he does have one, a very detailed one, to be honest. To give an idea how detailed, he said the outline is as thick as WoK.
There was a question that everyone knows here already, when the next WoT book comes out. Which we know as Nov. 2nd. Someone else had also asked when the final book is going to be released. Brandon said he is still hoping for late next year, but could be as late as Spring 2012. But stressed again they are still shooting for late 2011.
Hmm, what else. There was a question in regards to how he handles linguistics as well, but I can't really recall what the answer he had given now. I believe he had indicated he handles it different ways, depending on what kind of society he is trying to build.
Oh, and for those who might not have heard it on his previous tour stops, but it appears Brandon plans to put out two books for every 3 yr span for his Stormlight Archive series. So if it stays with the planned 10 books, we are looking at 15 years.
Finally, I asked Brandon later at the hotel if he has started A Memory of Light and he had said not yet. He is planning to take a short break until January 1st, which is when he would go right back into it. I said "Well, you deserve the break from any writing, even if only a few months." He responded with "Oh, not completely stopping writing, it would be like stop breathing for the next few months." He finished with saying he'll probably be writing a few short stories.
That's all I can think of right now. I asked him some other questions at the hotel, but they were more in conversation than any big news to splay online.
