When Ivy Bridge launched we all expected CPU prices to drop a little, instead .... Ivy bridge was introduced a little more expensive keeping the rest in pace.
Digitimes sources however now seem to indicate that Intel will most likely lower prices of Sandy Bridge processors in June-July and it will be very helpful in increasing demand for PCs in emerging markets. Intel has so far declined to comment on its pricing strategy between the old gen and new gen platforms. We'll report more when we get new information.
