Surely not these but the next batch of Fusion chips with "grown-up" CPU parts (Phenom/Athlon). Even the 11" Macbook Air's 1.4GHz Core2Duo ULV blows all of these chips out of the water.
True, maybe not Macbooks with Zacate, unless Apple wants something cheaper and lighter. And these parts aren't that far off from CULV Core 2 chips actually.
I think their version of cheaper and lighter will be the next step up from the A4, i.e. something ARM-based for their iOS devices. By avoiding the Core iX chips in the 11"/13" devices in favour of a faster GPU they've already demonstrated they're not keen to sacrifice computing power below a certain level.
