This game looks f*cking GREAT. Zelda trailers as of late have developed a tendency to drop my jaw in the non-figurative sense. I didn't think DS games could possibly look this good. And huzzah for touch screen puzzles! The first few seconds of the trailer made me think "Oh no, more tacked on, unnecessary Dawn of Sorrows touch screen action." But then I saw the boomerang. And then my pants got tight for some reason.
Also, is there any hope for some wi-fi Four Swords action? The concept of Four Swords has potential which has gone largely untapped thus far, and really, the idea is made for wi-fi play. Voice chatting during gameplay, even with those who don't have your friend code. It's a match made in TrueNerd heaven.
