Ali, I would not be surprised about the writer's block thing if it turns out to be true. And I think Martin has brought a lot of frustration onto himself with all of those initial promises that the book was nearly done and that fans would not have to wait long for it back when AFFC was released. At this point there is some sort of obvious problem with him finishing the book - it has been years - and he should just come out and be open and honest about it rather than being evasive.
I read the first Lynch book upon hearing that it could be read as a stand alone. It was mind candy - a gang of filthy mouthed young dudes for whom thieving is a literal religion - the fantasy equivalent of a heist movie. While fun, I have not run out to get the second book.
I read the Rothfuss because his publisher was proclaiming that the trilogy was finished and that they were just spacing out the releases for business purposes. Obviously that was less than the truth.
It was actually mediocre and needed editing horribly - but the writing was good enough that I will give his second book a try.
I actually wish Erikson would slow down to an every other year release schedule. His books are screaming for editing, and I strongly suspect given their length that rough drafts are being printed up and sent to the stores.
This series could be an all time fantasy masterpiece if they were only subject to a ruthless editor.
I honestly do not know if I will read the next Earth's Children book or not if it ever happens. The long delays combined with the ginormous drop in quality with the last book (which was pure excrement) are a huge turnoff for me. With a twelve year gap (or whatever is was), the book had better knock my socks off rather than be poop!
