On August 12th, LMB announced on her blog that Simon & Schuster updated their catalog to say that the hardcover will be available October 19th instead of November 2nd as previously announced. She did not provide a link but it was easy to find.
The publisher Baen still lists the book coming out November 2010. Amazon says they have them in stock, Oct 14th, "but may require an extra 1-2 days to process". Quoted price is $14.62 down from $25 MSRP (with free delivery in the US). Amazon.co.uk will only let one pre-order, for £13.29 which is (according to google) $21.05 USD, with free delivery in the UK. The Book Depository lists it as having $30 MSRP and will sell it for $22.50, free worldwide delivery. But still lists publication date as "02 November 2010". I've pre-ordered a while ago so I'm waiting for mine.
The eARC has been available at the usual copyright infringement locations since the beginning of August, when they became available on the publisher's site for $15.
LMB has allowed people to give out three copies in exchange for reviews. I paid for mine, so I don't feel obligated to write a review, but we'll see when I have the dead tree edition. Maybe I'll reread some of the previous books first. Does anyone want a copy? Yeah, I'm talking to myself.
EDIT: Just got an email from TBD stating "I am pleased to let you know that we have just received notification that your pre-ordered book has been made available by the publisher".
EDIT 2: Received, 2010-10-21.
