I just finished the book, and yeah, I kind of get the feeling maybe those publishers were getting a little impatient, being separated from their moneys for so long and all... But storm it, Sanderson! He left us with too many questions! With other books like the Stormlight Archives, you actually have all the little threads mostly wrapped up, but this... he just... it just... yeah, I don't really know how to explain the feeling, but I guess I should be kinda used to it by now. You read a lot of books, you have this happen way too much. Authors break their promises all the time.
