Anyone who thinks those are full motion videos need to have their head examined. They weren't FMVs on the 360 and they aren't on the Wii. Jesus, they're not even that good of quality! What the hell would make you think they're pre-rendered? What artist in their right mind would spend all that time and money doing a pre-rendered cutscene, but then make the backgrounds in the scenes look exactly as they would in-game?
So the more appropriate response would be that those shots are from cutscenes, and yes, the quality decreases during actual gameplay. Still, the fact that they are identical to the 360 version should be heartening to those hoping the graphics stand up to the 360 version.
