I have seen speculation that the MB will only come with the new 45nm Intel Penryn chips up to 2.4 ghz. Does anyone know anything about this speculation? I'm hoping that they'll come with the 2.5 because the 2.5ghz Penryn has twice as much L2 cache as the 2.4ghz penryn. My main question is this: does anyone have an idea of when Apple will be upgrading the macbook to include the 45nm chips? I was almost certain this would happen at MWSF since Intel announced the chips the week before at CES. However, I was sadly mistaken.
