What i've seen so far, if true, I don't see how it is so much better than the PS3.
Like from PS1 to PS2 is mind blowing. From PS2 to PS3 was a ridiculous change. But from PS3 to the rumored PS4 graphics, from what I see, it isn't that big of a difference. It hasn't made me go wow. Hopefully what I have seen is not really what the PS4 graphics will look like.
