This morning, Brandon Sanderson reported on Twitter and Facebook:
Ladies and gentlemen, A Memory of Light--the final book in The Wheel of Time--has been finished.
As for when the book will come out, Tor should do an announcement soon. Revisions will take a good six months. So fall, I expect.
Another common question: How many revisions will I do? The last two took about a dozen. (On no-wot books, I do about seven or eight.)
Sanderson's estimate of a fall release date is consistent with earlier statements he made on Twitter, comments made by Justin Golenbock, his publicist at Tor, and hints dropped by Orbit UK that we reported on earlier. As soon as we have an official release date from the publishers, we'll be sure to update our A Memory of Light info page to reflect that.
