Here is the full quote from a user in neogaf. - "Think about it this way. X360 is faster than PS3. Not just easier to program on, it's faster overall (although PS is faster/better in SOME areas). And yet no exclusive on X360 looks like The Last of Us. Halo 4 looks great. Gears blew my mind in 2006. And still, the best looking AAA game of this generation belongs to the supposedly weaker platform.
So if you think that the war is over because PS4 is 50% faster TODAY, then you're delusional. This is far from over, and will probably never be over, at least not this upcoming gen."
What this means is that all the fanboy arguments this gen were really dumb. 90% of multiplats looked better on 360 because it has always been the more powerful hardware.
The PS4 is more powerful than the X1 but in the end it will not matter because when you see a game's graphics you don't see the technical back end. You only see the pretty colors and such and all of that is subjective.
In conclusion, expect another 10 years of fanboy wars even though it's clear as day that PS4 is more powerful than X1 just as the 360 has always been significantly more powerful than the PS3.
