Rumors of a new Mac Book Pro

From IGN:

"Further credential for the rumors has now come to light via the MiniBatteryLogger tracking logs. The public database has apparently identified a new MacBook model somewhere in the wild, notable for its system identifier label of "MacBookPro4,1". Current MacBook Pro models are labeled MacBookPro3,1, so the new identifier certainly seems promising.

Adding further support to the rumor, MacRumors.com reports that its sources have identified the IP address of the MacBookPro4,1 as originating from Apple. The site also notes that Mac OS X 10.5.2 also makes reference to the MacBookPro4,1, which means we should see the new models before the next OS X revision."
