So I just saw a new article about Winds of Winter and found a statement from GRRM interesting. He said that he hope WoW will be out in 2018 and maybe even two books will be out in 2018. So I guess he must be holding back WoW in case some plot takes a different turn then he can go back and correct it. I sure hope this mean that we won't have to wait 10 years for a Dream of Spring after he finally finishes WoW. Here is to hoping anyways.
