I found this video while browsing YouTube and I thought it was really well made. Just thought I'd post it for you guys to check it out. According to the user who made it, they made a follow-up video that said the movie was only going to be available to people in Japan in one year, according to Nintendo's Legal Team.
Anyways, here it is! =3

OMG that is epic. I love the suits, and that was sweet how they actually went on a go kart track.
