Hmph. I had this argument a while ago with WereKitten, and frankly, there is no denying these 720p images produce a lot of pixelation in the ground textures, which was not as evident in the original game. Granted, AA would make things better, but that would (in effect) remove even more detail from the textures, and even then it does not come free. Obviously, because the game was never designed to be displayed at such high resolutions, Nintendo didn't spend as much time adding details to and/or supersampling their textures. If the game had been designed for HD output, it likely would have been (a little) more expensive to produce, which, as some might recall, was my argument in that original debate.
WereKitten is still right in theory that it would better Wii games with no effective loss to developers (just display them in a higher resolution), but in practice I think it would definitely cost some money (if they were unwilling to ignore these issues).
For comparison (demo image, but still):
Not nearly as much of a problem, don't you think?
