According to a scrolling notice recently put up at the DOD BAH query page, "2010 BAH Rates will be available 17 December 2009." It is great to have a date so that I can stop checking every darn day. I'll let you know when the actual rates come out (before, on or after that date.)
Rates are available (as of 12/15/2009) at Military.com's BAH Page.
