It's actually boils down to whether the developer of the game actually cares to make the graphics on one platform as good as on another. It all boils down to their dev team, their ability, etc.

Guitar Hero 3 graphics on Wii setanding graphics on PS3 if you level the playing field by setting both to 480p.

But FFXIII now under controversy because it's said that the 360 version has inferior graphics compared to PS3 version, even at native res.
