Since the release of the 15 inch MacBook Pro in January, speculation on the forthcoming Apple laptops is spreading throughout the net. Meanwhile, MacosXrumors has received a very unexpected report, providing information about one of the forthcoming MacBook Pros.

The sources that can be qualified as "very reliable" (yes you read it well), are claiming that Apple plans to keep similar display size for its entry level Mac Book Pro by releasing what sources called an "ultra-thin 12 inch Mac Book Pro".

Neither release timeframe nor technical specifications were provided by the sources but we may expect this new Mac Book Pro to arrive late in the second quarter of this year. As for the technical specs, we prefer not to speculate on them so as to keep this report as factual as possible.

The current 12 inch Powerbook G4 is 1.18 inch thick while the PowerBook G4 17 inch and the Mac Book Pro are 1 inch thick. We can expect the 12 inch Mac Book Pro to get at least as thin as the rest of the line-up and possibly even thinner.

The sources also believe that the rumoured 13 inch form factor could rather be used for Apple's entry-level laptops (iBooks or MacBooks).
