Well the actual in mid 2010. The book remains to be 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 a fan.
All that negativity aside, there is a reasons why fans of his books gripe and vent whilst still being wait following a four year hiatus as well as a six year hiatus. The books are simply just that good.
I will provide him with his due, he will take time because he desires to only released an exceptional product.
More positive news is always that there is a HBO miniseries, that's forthcoming, determined by this series. With the quality with the books, as well as the quality that HBO does using their series, I expect it will likely be great. Perhaps the HBO leg breakers will hold his feet on the fire in completing his novels.
I hope that MR. Martin will decrease his many side projects, convention attendances and book signings and simply get on the writing. This includes minimizing his involvement while using HBO series. Trust it is good hands, George. There will only have a lot more fans clamoring for his next book release after the series is released. Get to it George, were waiting.
