MacBook Pro refresh coming before Christmas?

AI reports that the MacBook Pro line will receive minor processor updates before the holiday shopping season.  In fact, they say the updates should come before the end of the month.

According to people with proven insight into Apple’s future product plans, the late-2011 MacBook Pro refresh will deliver marginal speed bumps to the notebooks’ Core i-Series of Sandy Bridge processors but will otherwise introduce no material changes over the existing models.

While precise timing for the update may change, those same people say the Mac maker currently anticipates an introduction of the refreshed line before the end of the month,

The report seems to stem from the recent release of Intel Core i7 2700 series processors fit for use in MacBook Pros (right).

This seems to fly counter to earlier reports from MacRumors that the next update to the MacBook Pro line would be a big redesign.

MacRumors has heard reliable confirmation that the next revision of Apple’s MacBook Pro line will utilize a new case design for the first time in several years.

For what it is worth, we’re seeing no hiccups in the supply chain on current models.  Silent updates aren’t unheard of however.
