I think he is catching on with Sony's PR game.
He should've announced a recruitment event for ex-studio evolution workers and we would go full circle. :D
Well... regardless of PR stuff i think he is right. If theres no significant upgrade, the consumers won't get it. And to get a significant upgrade means to burn early adopters, wich isn't a very good idea for your next system.
I don't think this PS4K thing is gonna end any better than the new 3DS.
