Video game systems could never do Anti Aliasing justic as like on pc, so you can't compare the two. For instance fear has a setting of up to 16x, and they also have other image enhancing settings that i can't remember roght now that few pc's can actually run decently. Nintendo might have vaguely invented aa, but the pc evolved it into something that's used today in just about every program. As for the jaggies in zelda that should't be that important since the game has changed from what was shown at e3 or even what they had last year, and a game doesn't have to be 120% just to be good.
P.S I wonder what will become of tingle will it come stateside?
