WWDC is just under a week away and a spec sheet appears to have leaked that details the next-generation 13-inch MacBook Pro. Chinese site Weiphone claims a US Apple employee snapped the spec sheet which hints at a 13.3-inch display with 1280 x 800 resolution and 2.5GHz dual-core Intel i5. Intel's HD Graphics 4000 is also reportedly on board, alongside Thunderbolt and two USB 3.0 ports — indicating this is an Ivy Bridge refresh of Apple's MacBook Pro line. The size dimensions remain the same as the existing 13-inch MacBook Pro, but the weight is up from 2.04kg to 2.06kg — suggesting there's no new radical design on this particular model. The image also refers to OS X as "Mac OS X" rather than the simple "OS X" branding that Apple has adopted with OS X Mountain Lion, which could suggest it may not ship with the new operating system.

Although the image could easily be faked in a number of ways, we scanned the barcode and it does provide an 826-9882-A product code that's included on the photo. Apple's Thunderbolt ports leaked out in a similar manner last year, proving to be genuine. We can't be certain either way, but these specifications could represent a base model configuration with multiple display resolution choices. Apple offers multiple resolutions and finishes for its 15-inch models, but its 13-inch MacBook Pro is currently only available with a glossy 1280 x 800 display. Previous rumors suggested that Apple could be planning Retina Displays and an ultrathin design for its next-generation 15-inch MacBook Pro model.

Thanks, Josh!
