Last I heard it will be out next October. It was originally supposed to come out this year but he's had a few RL issues that have caused the book to be delayed. Really excited for the next one

As for me I'm trying to burn through the WoT series so I can read The Gathering Storm. I'd been really disillusioned with the series after waiting for the abominations that were books 8-9-10, but Sanderson seams to have returned the series back to what made the first 5 books so good.
