Support files for unreleased MacBook Pro computers have been discovered in the latest devloper build (10C531) of Mac OS X 10.6.2. The new build was seeded to developers just a few days ago, and includes a few references to the unreleased 6,1 and 6,2 MacBook Pro models. The latest available MacBook Pros carry a 5,x model number, and were last updated in June. No rumors of MacBook Pro refreshes have surfaced recently, although previous reports have suggested that Core i7-based processors could be integrated into MacBook Pros by late 2009 to early 2010.

Several people have noticed and pointed out that Apple’s user guide for its new Magic Mouse makes a reference to the not-yet-released Mac OS X v10.6.2. The mention of OS X 10.6.2 suggests that Apple plans or at least did plan for the update to be released to consumers around the product launch.
