True, but the Wii shouldn't be compared to PlayStation when it comes to visuals. Wii has a knack for giving vibrant color depth and gloss-like light reflections. Everything feels "bubbly" with its 3D depth as well. This doesn't represent the Wii's look at all, and I've never seen a more visually disappointing Wii game.
I wouldn't be surprised if these were PSP screenshots put in the wrong section on Gamespot.
