I made a post some time ago trying to work out the price for optimum revenue for Sony:

I figured out, based on current demand situations (ie - Same prices of competitors (at this point, the 360 hadn't had its price cut yet, or it was just about to, and same number of games, etc) that the optimum price point would be $345 in the US.
