Did you know that Square-Enix has their own, official YouTube channel? It is the Japanese branch of the company, so you can expect all of the featured videos to be in Japanese.
In any case, a few days ago they updated three volumes of "Theatre Bearers", a series of videos focusing on the upcoming Crystal Bearers for the Wii. They are narrated by a cartoony mog and a bomb. As I mentioned earlier, Square-Enix's channel is Japan focused, so these three videos are entirely in Japanese.
