In the period following Pentium 166 MMX and Pentium Pro, the pricing behavior had always been in a consistent pattern. When a new cpu/speed grade is introduced, this becomes the top-end and commands a price in the vicinity of 700 USD. This top-end price will be cut to almost half once a new cpu/speed grade is introduced to the market. In the process, the top-end ends up as a mainstream. The one that used to be in the mainstream is cut off the production line or pushed back to the budget line, most likely the former because there is a product line for the budget line.
We have yet to see a voluntary Intel price drop such that its price level approximates its equivalent AMD cpu, much more without being pushed by the introduction of a new cpu/speed grade. So, it is but logical that until a new cpu/speed grade is introduced there will be no price drop.
