Well here we are in mid 2010. The book remains in the process to be written. Six many years of writing a "partially completed" book. With two more books meant to come after that! It is extremely frustrating to become fan.
All that negativity aside, there can be a reason fans of his books gripe and vent and still wait from a four year hiatus as well as a six year hiatus. The books are simply that good.
I will give him his due, he takes time while he desires to only create an exceptional product.
More positive news is that there can be a HBO miniseries, that is certainly forthcoming, according to this series. With the quality in the books, as well as the quality that HBO does making use of their series, I expect it'll be great. Perhaps the HBO leg breakers will hold his feet for the fire in completing his novels.
I hope that MR. Martin will decrease his dozens of side projects, convention attendances and book signings and merely get for the writing. This includes minimizing his involvement with the HBO series. Trust it is at good hands, George. There will only have increasingly more fans clamoring for his next book release as soon as the series happens. Get to it George, we're waiting.
