Well the actual in mid 2010. The book remains to be within the process of being written. Six numerous years of writing a "partially completed" book. With two more books designed to come after that! It is extremely frustrating becoming a fan.
All that negativity aside, there is really a reason why fans of his books gripe and vent yet still wait after having a college hiatus followed by a six year hiatus. The books are simply just that good. I will provide him with his due, he needs time to work as he wants to only released an outstanding product.
More positive news is that there is really a HBO miniseries, that is forthcoming, depending on this series. With the quality from the books, and also the quality that HBO does using their series, I expect it'll be great. Perhaps the HBO leg breakers will hold his feet towards the fire in completing his novels.
I hope that MR. Martin will decrease his many side projects, convention attendances and book signings and just get towards the writing. This includes minimizing his involvement with the HBO series. Trust it is good hands, George. There will just have a lot more fans clamoring for his next book release after the series arrives. Get to it George, we're waiting.
