Well here we are in mid 2010. The book is still in the process to be written. Six a lot of writing a "partially completed" book. With two more books likely to come and then! It is extremely frustrating becoming a fan.
All that negativity aside, there can be a reasons why fans of his books gripe and vent but still wait after having a 4 year hiatus then a six year hiatus. The books are simply just that good.
I will give him his due, he takes time because he really wants to only released an outstanding product.
More positive news is the fact that there can be a HBO miniseries, that's forthcoming, determined by this series. With the quality in the books, along with the quality that HBO does using series, I expect it will likely be great. Perhaps the HBO leg breakers will hold his feet to 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 to the writing. This includes minimizing his involvement using the HBO series. Trust it is within good hands, George. There will just have increasingly more fans clamoring for his next book release after the series comes out. Get to it George, we have been waiting.
