The MacBook Pro will likely be updated soon, but I expect Apple is waiting for the new mobile processors because their TDP and power draws will be lower then the overclocked chips Apple is using at the top-end of the iMac line.
And I would expect Apple to move to Montevina rather then do the "Santa Rosa Special" on the current MBP systemboard since the latter will also increase heat generation and power draw, both of which are undesirable in a mobile platform. Hence no simultaneous MB Pro announcement.
Now watch them announce new MBPs tomorrow with the overclocked parts. 😛
