I've heard October, but I have also heard the slightly more vague, "before the end of 2009". Being a game designer myself, I can attest to a lack of control on certain levels of the process. Once the rules are done (and I am certain they are), you have to wait for layout, proofing, and printing, and if you're printing abroad, there are lead times involved.
I'll be pleasantly surprised if it hits in October, but it'll be a welcome holiday present if it arrives in December.
