According to his website:
As of yesterday, STORMLIGHT #3 is at 53% on his website. I think Brandon's current plan is to have the book edited and turned in by the end of this year and out in early 2017.
Wait, I thought that the Stormlight Archive is a five book series, to be followed by another five book "sequel series" - but that the five books should be readable as a complete series of their own.Right?
Sort of. The two halves will be more closely connected than, say the three MISTBORN trilogies (and especially between the three trilogies and the Wax & Wayne side-quartet), but they won't necessarily need to be read straight though. I think he's indicated that Book 5 won't end on a massive cliffhanger that leaves you hanging for years whilst he works on the second MISTBORN trilogy.
However, it is roughly 1.5-3 years between every individual installment of most series', since with the exception of Mistborn I believe, almost all of his books are doorstoppers.
STORMLIGHT (900-1100 pages in hardcover) are the really massive books. The core MISTBORN trilogies will be long (500-600 pages in hardcover) but still quite a bit shorter than STORMLIGHT, and everything else should be a lot shorter. His YA and children's books are very short and he can churn them out in a couple of months each.
With the rotation he does it's very easy for delays to cascade into other delays, and he keeps adding new projects onto the pile, that's it's very possible a lot of series' could be unfinished.
More to the point is the fact that his adult fantasy novels are all set in the same universe and all telling the same story, and that story will risk being unfinished unless he gets a handle on how he's going to do it. The Cosmere mega-series (incorporating STORMLIGHT, MISTBORN, ELANTRIS, WARBREAKER, DRAGONSTEEL and a number of other works) is planned to be something like 45 books in length and so far we've only had 10 of them in 11 years. I mean, that's still awesome given he's also written another 14 novels outside the Cosmere in the same period, but if he wants to get the Cosmere wrapped up in a reasonable timeframe he needs to maybe have another thing about this, especially if he slows down as he gets older.
Since it was only the first 6 books which Jordan really churned out I always just assumed that he had at least written rough versions of them before the first was published, since the first several came out basically yearly. (Generally publishers don't like authors to put out more than 1/yr as they start to cannibalize their own sales. I know that some authors actually write nonfiction on the side during their downtime because it doesn't take them a full year to write a novel.)
THE EYE OF THE WORLD was finished in 1988 but not published until 1990. He had finished THE GREAT HUNT and was into THE DRAGON REBORN by the time the first book came out. He just stayed ahead of the train by writing non-stop until Book 7, when he was told by his doctor and family to take the pedal off the metal somewhat.
People that are clutching their pearls over the possibility of HBO producing this for fear of 'blood and sex' do realize that WoT had plenty of both, right? I think HBO could do a fantastic adaptation of the series personally. I'll agree that GoT sometimes goes overboard but in general the show has been great and I'm glad we got to see it.
But absolutely nowhere near as much as GoT, and no on-screen sex at all, although there's a fair bit of nudity.
According to those in the know, HBO weren't interested in the rights when they were being shopped around and aren't the studio that's paid for them. The deal has actually been done, we're just waiting for the official announcement to come through.
