I am going to get it. I have always loved everything PlayStation has done throughout the years.
As far as the comments go for "Might as well build a PC". You seem to be forgetting that convenience is the biggest seller. The average joe can't build a gaming PC and can't afford the cost to have one built for him, having a $400 piece of hardware (as that is what I guess the cost will be) with easy hookup to the TV and a familiar controller is just more convenient. Consoles aren't going anywhere, however, I do believe we are approaching a graphics plateau, where the games wont be able to look any better and consoles will have to do what Nintendo has been doing, innovating in the gameplay market, to ever sell a new console.
