GRRM’s official site has been updated with a signficant new update in the "Update" section, bringing us up to speed on where exactly he is in his work and where he hopes to get. For those who don’t want any spoilers regarding who our POV characters are, it may be best to avoid it as George discusses POV characters and other information of the kind.
For those who just want to know where things stand, a brief excerpt with the nitty-gritty:
“As of this writing, A DANCE WITH DRAGONS consists of some twenty-two finished chapters totalling 542 manuscript pages, plus another 100 to 150 pages of partial chapters, early drafts, scenes, and fragments. Some of that material will need to be revised, and of course much more remains to be written. My hope is to bring the book in at around 1200 to 1300 pages.
“And before anyone writes me asking, yes, there is a third Dunk and Egg novella in the works as well. It’s maybe three-quarters done, and sometime soon I want to find the time to finish that one too.
“Anyway, that’s how things stand at the end of January. I will try and update again around the beginning of April.”
