What will Book 13 & 14 be called?
Book 13 will be TOWERS OF MIDNIGHT. Book 14 will be A MEMORY OF LIGHT.
When will they be published?
Tor is publishing TOWERS OF MIDNIGHT on November 2nd, 2010. According to Brandon Sanderson's blog, he intends to begin work on A MEMORY OF LIGHT in January 2011 and anticipates it's release no later than Spring 2012. This will be the final Wheel of Time novel.
And so, we're entering the "refresh and work on side projects" stage of the writing process. I did this after The Gathering Storm, and I really need it now. I am therefore taking time off between now and January first. I get to write anything I want. It will probably be bizarre and unexpected; things that keep me fresh, things I haven't tried before.
I ask your forbearance. I do believe that as a writer who has begun series, it is my responsibility to see that the other pieces of the story are written in a timely manner. However—and it may seem odd—I need to work on these other things to keep my next Wheel of Time and Stormlight installments good. It's how my process works.
So, that's the first warning. I'm taking a break for three months. The second warning is that I can't promise I'll hit the final deadline on the Wheel of Time series. (The last one was supposed to be out in November 2011.) The problem is this: starting January, it will have been three years since I read the Wheel of Time series start to finish. That's too long. I'm starting to forget things. I won't feel comfortable starting the final book until I've done another re-read, and this is going to slow me down by three or four months. It's an unexpected delay I didn't fit into my original projections of how long it would take me to write the books.
If I miss the deadline (which is more likely than not) it won't be by much. A few months, likely the same amount of time it takes me to do the re-read. But it is what must be done. So, I'd suggest that we set MARCH 2012 as the expected date of A Memory of Light. I suspect there will be some grumbling about this, but I feel I should let you know now, rather than later. It won't be an enormous delay, however. If my previous track record earns me anything, I hope it is the benefit of the doubt when it comes to me promising the release dates of books. I won't leave you hanging too long.
