Outside of the Skyward Sword trailer shown at Nintendo's pre-Tokyo Game Show 3DS conference last night, I think there was only one other video (of which there were many) that caught my eye. It was the new Square Enix game Bravely Default: Flying Fairy.
Specifically, the art style. "Wow," is pretty much all I can say. That's one way to design around hardware limitations. It's not so apparent in the screenshots as it is in the trailer, so give that a watch.
