Apple Insider posted a story that Apple is reportedly preparing a refresh of its professional notebook line ahead of the holiday shopping season

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, possible following the close of the company's Back-to-School promotion, which ends on September 20th.
