MacBooks getting a speed bump soon?

Apple's MacBook line of consumer portables haven't been updated since May, so it's not entirely surprising to hear that the black and white notebooks might be getting a speed bump soon. Think Secret reports that the MacBook line will see a minor hardware refresh following the release of Leopard (on the 26th?); the new machines "could be [in] consumer hands by the first half of November, if not sooner." What's unclear is exactly how the machines will be upgraded--will the MacBooks simply get bumps in CPU clock speed or will they move to Intel's new Santa Rosa architecture? Either way, that will bring the high-end MacBooks suspiciously close to the MacBook Pro line in terms of specs, so might a MacBook Pro update be in the cards as well? No such luck if you believe Think Secret: "Apple is not expected to update the MacBook Pro before the end of the year, and sources at this time don't expect any other Mac hardware to see a revision before the holidays."
