I'd hang on for a few more days, if I were you -- unless of course you want the 17" with the Superdrive. If these new iMac are going to arrive, around now is the right timing. If they don't pop up in the next week or so, they'll be too late for the Christmas season, and Apple may elect to hold them until MW-SF. Given what I've heard, I'd bet on the next week or so -- unless thousands of the new models are currently sitting on container ships sitting at anchor off of the Port of Los Angeles.
