Earlier today, a Chinese forum post on Weiphone claimed to have the specs for the new 13" MacBook Pro revision. Disappointingly, the changes were minor with no evidence of a new design or the use of any high resolution Retina display.
The original poster has since edited his post with additional claims for the 15" MacBook Pro update. The specs listed include:
New Macbook Pro 15 inch:
i7 2820 2.3GHZ/2x2GB/500GB
i7 2860 2.5GHZ/2x4GB/750GB
Card is NV GT650M 1G
What's questionable about these specs is that the processors listed are previous generation Intel processors and not the new Ivy Bridge ones that we have been expecting. While representing a slight upgrade to the existing 15" MacBook Pro models, it's hard to believe that Apple would use last year's processors in their upgrade.
