Sony isn't going to jump on the PS4 when the PS3 software is at its peak....
They have zero icentive to start early next gen, and I doubt many publishers are pushing them to jump to the next gen ( except epic because they want to sell more unreal engines...).
On a personal level I am totally happy with the games we see this gen and I don't really see the need for more powerfull consoles yet ( because stuff like the epic demo of next gen graphics might look cool but it's going to cost a fortune to develop and I feel like the graphics are good enough right now, better shadows or lightning isn't going to improve my gaming experience..)
