You don't need to, it seems like Eidos CEO hinted it. But anyway, I'm pretty sure EDGE leak was spot. Hopefully they do release console that is weaker, that can't play used games, that requires internet connection and also comes with "NASA approved Kinect camera" for arm waving and rewinding of netflix movies and they crash and burn, hopefully going out of console business because they have no interest in actually delivering quality content without milking the shit out of people. Paul Thurrott did say that their strategy with Xbox is severly lacking, I can see why.
You either deliver something revolutionary and exciting (think first Iphone) and then continue riding on its success while always having top hardware and software you can engineer, or you come up with Kinect like turd and hope that shit is going to stick. Nintendo thought they had it, after the success with Wii, so they released "new, exciting way to play" and now it seems like numbers aren't exactly flattering and casual-mania has died down. The only difference is that I'm actually sorry for Nintendo as gaming is their only revenue stream and they can't go in hardware/moneyhatting competition with MS or Sony so thats the only way they actually can go.
As for Sony, depending on pricing, they can kill of Durango without much problems. Better mutliplats, PSeye camera, Move games, Netflix, great exclusives like UC/GT and free online. They just have to find a way to present that to customers instead of fucking ads like crying baby and "Is Cell even smarter than you".
