Activision shows off a number of levels from all three next-gen versions of its WWII sequel, and Gamespot grabbed the controls to compare them all.
"It's worth noting that the 360 and PS3 versions are identical in terms of content; the only difference we noticed is that you can thrust with the sixaxis controller on the PS3 to make your character do his melee attack (though you can still use the button if you want). The games looked quite similar, too, from what we could tell. The level of detail in the maps and characters has been noticeably ramped up from Call of Duty 2, such as with the aforementioned individual grass blades and rays of light filtering through the trees. The characters' facial expressions, clothing, and animations are also appreciably more realistic than in the past. You'd be hard pressed to say which version looks better, especially since they're both running in 720p resolution, but neither one is a slouch in the visual department.
The Wii version, as it turns out, is content-identical to the 360 and PS3 versions, for the most part. It's reasonable to expect that the relatively weaker system will have fewer enemies and simplified geometry in some parts, but in terms of storyline, basic level design, and so on, you're getting the same game across all three platforms. The Wii version naturally doesn't feature the extreme detail of the other versions, but it does play much like we're coming to expect first-person shooters to play on this unique new platform. Like Metroid Prime 3 and Red Steel, COD3 has you using the remote for fine aiming, and moving the cursor to the edges of the screen will make you turn. The analog stick on the nunchuk makes you move, and the various other buttons of the Wii's controllers let you perform other actions like ducking, jumping, and going to iron sights."
