Rumors of a MacBook Pro update have been going around for a while and now additional evidence of such an update has surfaced. A picture showing the Best Buy inventory system has leaked and it includes a listing for a dummy unit for an updated MacBook Pro line. According to the leak, the new units will include a $1,199 model, which is the base price for the current 13-inch MacBook Pro and indicates that the upcoming refresh will probably lack a price change. In case you’re not the patient type, the system also lists March 11th 2011, as the release date for the upcoming items, though there isn’t any way to confirm if the dates are accurate or not. Considering that it’s been a while since the MacBook Pros have been updated, perhaps we are going to see some announcements soon.
