Due to the confusion regarding the release date for AFfC, here’s the official word:
No, the book is not coming out in July, despite what any book store or friend of a friend might tell you. Even Random House’s website is inaccurate at present.
The book isn’t coming out in August, either.
GRRM has said that he thinks late September or October are probable, as those are the target dates which his publishers (both the US and the UK) are working towards. This isn’t absolutely fixed in stone, however, from anything we’ve been told.
