I don't think price is really that big of deal.
Right now the PS3 sells despite being the most expensive of the 3 consoles because there is a perception the value it brings is worth the price ( namely Blue Ray).
Sony just needs to keep adding more value to keep sales going.
Sony has never been a Compary to heavily drop prices to get increased sales. Their electronics sells well despite being more expensive than the one from the competition because it is perceived to be superior to it....
The price of the PS3 is by the way not that far from the price of PS2 at the same time in its life.
299$ of 2002 is 351$ of 2007 with inflation factored in....
