Lynch obviously has some personal problems he needs to work through. I hope he's successful. I love the first two books.
But even if he was just a slow writer, I'd be willing to overlook long delays. Because unlike many genre authors, he's given us two largely self-contained novels in this series. Yes, Red Skies ended on a bit of a cliff-hanger, but it still had pretty solid resolution overall. Both books so far had a nice "beginning, middle, and end" arc to them.
Unlike others some others I could mention *cough* Rothfuss *cough*
