According to sources close to the heart of the matter, Apple allegedly refused to adopt Intel's Arrandale and the Calpella platform in its default form. In order for Apple to implement Calpella design with their next refresh of Mac mini / MacBook / MacBook Pro lines, Intel will have to provide Apple with the 32nm version without the integrated graphics part. Again, we cannot confirm the information about the replacement CPU, we only know that Apple rejected Arrandale.
Apple was always going to refuse to adopt Intel's Calpella platform in its default form, as it's not adopted default forms of previous platforms. Apple refusing Arrandale wholesale is another ball game. The Arrandale could have the graphics turned off anyhow, so if they're demanding something else - wonder what that might be. I'd imagine Apple's been working with Intel on chipsets anyhow (esp. in the light of Light Peak work).
Seeing as though we wouldn't likely hear of a new Intel chip if they had one being lined up for Apple anyhow, it's more of a case of waiting 1-2 months.
Just being able to have both Nvidia run concurrently, and sorting heat issues from that would be a boost to the MBP. There are updated chips Apple could use, if they didn't go Arrandale in February.
Would Apple be that behind if they didn't go Arrandale come February for the MBP?
