Beginning of KISHIN

Famitsu.com put online these 3 images from the technical demo of a new japanese game for Xbox 360 called Beginning of KISHIN. The game should be unveiled completely during the TGS, but if these screens are really in realtime (and they should be), it's VERY impressive.
Update : Famitsu also says that they do not know if it is game footage or a CG movie from the game. It may not be a tech demo.
Update 2: This was a tech demo, but of a movie codec. So more than likely this is CG footage.
