This just goes to show, price and quality don't always match.
Take Wii and Xbox360, compare that to the price of PS3.
How many people have a 360 compared to PS3? I rest my case
Getting a PS3 is so stupid, most of the games are on 360 anyway.
Having a limited edition run is a great way of making money. It's up to the consumers to buy it. Naturally all copies will be sold, one way or another.
