I'm trying to order a copy through Barnes and Noble.com. BN says they expected it to ship on July 26, 2012. It didn't ship. BN now says the release date is January 8, 2013.
Hilariously, I just got the automated e-mail from BN asking me to review my recent purchase of the Rise of the Runelords Anniversary Edition, despite the fact that it hasn't shipped....
