For those who may not know, the game is based off of The Melancholy of Haruhi Suzumiya and Aya Hirano is the actual voice actress of Haruhi in Japan. The dance featured is also from hare Hare Yukai, which is the ending theme for the anime.

The game is currently set for release in Japan, January 22nd 2009. No current plans for an American release have been announced. You can pre-order the japanese version at NCSX.com or Play-asia.com, as well as a deluxe edition which features a posable Haruhi Suzumiya figure in her schoolgirl uniform.

I can say I was sold on the game for it being from the anime series already, but this trailer sealed the deal.
