I have it for PS3 and honestly on my 1080p display it looks better than those images.
Of cause it does look better. Every game does
It's partly because of what nasos_333 says, the quality of your TV/monitor, but a big part plays the viewing distance as well.
Console games are developed to be played on a TV and normally you sit a bit further away from your TV than from a PC monitor. And this lessens the negative impact of lower AA, texture quality etc on the image quality to a certain degree.
I have unfortunately no TV, only a monitor I use for both, PC and console games, but for console games the first thing I do before playing is moving my chair back to get a comparable distance like I had with a TV since without that even games like Uncharted 3 look very mediocre from such a short distance instead of jaw dropping it normally does.
Therefore graphic comparisons like this are almost never a 100% accurate representation of how the game looks, but they're still interesting for comparison because not only does the PS3 version look in reality better than on these pictures, the Xbox360 version does as well and in the end has the better image quality in this case. For multi console owners good to know.
