So there are rumors going around the web about the reason why Phil Harrison has left Sony. It seems the talks of PS4 has burned the poor guy out. Now the expectations for the Sony PS4 are huge. Obviously there are rumors around that PS4 will try to take the concept of social gaming to the whole new level (sort of like the transition of Web 1.0 to Web 2.0). You can also expect more interaction between the console and the players (but details are not yet released). I can tell you what PS4 won’t be – a big black box with huge fans. But that’s all we can tell at this point.
