Lets say PS3 always ran at 720p/30 (which is not true btw) and PS4 will always run at 1080p/60 then it needs 4x the power to accomplish that resolution and framerate increase.
So then we have 6x the power of a PS3 left for bigger worlds etc.
Btw was the PS3 20x more powerful than a PS2? I guess PS5 will be 5x more powerful than PS4 then.
