Regardless of when it comes out, this'll be my first Day 1 purchase since Smash Bros. (I can't see myself purchasing anything on Day 1 in the next year.) I can't believe how excited a 45-second trailer made me. So awesome.
A couple Kotaku commenters mentioned the subtitle having the initials DS. If it turns out NOT to be a coincidence, I'll be very upset. I mean, I love my DS, but shaking my Wii remote around made the game so much more fun. I feel like continuing my aborted second playthrough right now!
