I have to agree with PS3GAMER, PC will always be superior graphics wise. PS4 wasn't needed, It's very expensive ($530?) and only a bit better (graphic wise) then PS3 and of course, some gimmicks to justify a new console and allow Sony so say they're innovating. Sure, It has way more graphic potential, but how long did It take to use all of PS3 potential? 6~7 years?
By the time we get to see PS4 at It's best we'll already have PS5. Consoles should be cheap or else It just won't sell much. People who are willing to afford A LOT to have amazing graphics spend that money on powerful PCs.
