May imply November launch
An unusual listing in Apple's online store may back claims of a MacBook Pro refresh happening in the next few weeks. If a store visitor searches for the term "MacBook Pro," one of the current listings is for an unidentified "MacBook Pro Memory Model," with availability quoted as "Coming in November." Clicking on the listing generates an error message.
There is in fact said to have been another such listing as recently as Monday night. In both cases, URLs appear to contain references to different clock speeds, namely 2.33 and 2.4GHz; if so they may indicate Apple's choice of quad-core Core i7 processors. Apple would presumably be releasing new MacBook Pros in November, although since the listings are for memory and not computers, the Pros themselves could conceivably ship earlier.
