Hell, I dont think Sony has a shot until they get that sucker down 200$ at LEAST. We already know what a PS3 sells like when its $500 instead of $600. Have you all forgotten? We HAD one of those. And it changed nothing. The sales were plummeting then and they are plummeting now. but at $399 it would have a good chance to take off into space.
However as a business they arent going to chuck 2Billion to the wind on the chance that it would send the PS3 to heaven. That would be idiotic.
