Well the actual 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 becoming a fan.
All that negativity aside, there is a good reason that 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 only that good.
I will give him his due, he will take time while he would like to only put out an excellent product.
More positive news is the fact that there is a HBO miniseries, which is forthcoming, determined by this series. With the quality from 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 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 simply get to the writing. This includes minimizing his involvement with all the HBO series. Trust it is in good hands, George. There will have only a lot more fans clamoring for his next book release following your series comes out. Get to it George, we have been waiting.
