Actually, Intel already announced the price cuts and they should all be in effect by the 15th of November. None of the price cuts are on any of the popular CPU's.
The i7's are priced so far above most all the other CPU's, they really do not have to lower prices. The current Wolfdale/Penryn cores are faster than anything AMD has to offer at the moment, so Intel really has no incentive to lower the prices much, if at all.
The big downside to having no competition in the upper end of the CPU market.
