I have some economics background, so maybe I can shed some light on this.
In any situation, you try to balance the supply against demand through changing the price. If you set the price too high, nobody buys your product, and you're stuck with a lot of inventory on your shelves. If you set the price too low, you run out of inventory, anger customers by having nothing in stock, not to mention lose out on some of your margins as opportunistic customers will resell what they bought for a higher price (X360 launch, anyone?). Newegg's a pretty big company with a rather solid track record; I don't think they set the price where it is because they don't believe that they can sell their entire inventory of their C2D processors at the price they are selling them for. And, to be honest, they're probably right; the E6600 and E6700 are two of the best chips money can buy, even at an inflated price, and they'll still sell at the prices that some of you are complaining about. If you don't like the price, don't buy it until the prices drop or shop somewhere else; it's that simple. Nobody's holding a gun to your head and telling you that you have to buy an E6700 from Newegg and only an E6700 from only Newegg.
