Unreleased Macbook Pro referenced

Before you even dare pull the trigger on a Macbook Pro purchase, it seems Apple is already working on an upgrade for the Macbook and the Macbook Pro.

In a list of support files in Apple's 10.6.2 Snow Leopard update, "MacBookPro6_1" and "MacBookPro6_2" are referenced so it's probably safe to say that a release could be overseen in late 2009 or early 2010. Today's newer MacBook Pro's only carry a 5,5 model number.

Could it be Nehalem coming to the Pro? How about a Blu-ray burner?
