Just a clarification, if a 45nm core i7 mobile variant skips the MB and MBP pro line, we're talking about Westmere. Westmere, like penryn, is a die shrink of a previous architecture technology.
For example, penryn was largely the same as merom in architecture, but featured a die shrink from 65nm to 45nm (with some improvements, like some SSE4 instructions).
Similarly, westmere will be a 32nm shrink of the 45nm nehalem core, but with some minor enhancements, such as encryption/decryption instructions.
This would also be the first time that a processor with an integrated graphics controller and quickpath technology would show up in any macbook variant.
Be aware that Q4 09 for any macbook update is highly unlikely. Apple doesn't typically update here (october would be too early to get these chips). Also be aware Intel is prepared to push back the release of the Calpella platform in order to ensure montevina inventory is cleared out and the economy will show favor to its new platform.
