So I haven't been able to play the Live demo as I do not have a Japanese Live account, however I do have a PSN account for that territory - so I downloaded the demo. It's an impressive hack and slash, and is certainly a step up over both Devil May Cry 4 & Ninja Gaiden 2. Graphically the game is impressive, although it's a bit blurry and washed out (the 360 version is meant to be sharper) it certainly isn't a slouch. Frame-Rate issues that supposedly plagued the PS3 version seems to be sorted and it did not feel at all choppy. The amount of moves available will take a long time to master, but it looks from the demo that it is well worth doing so. Out in early 2010 in NA & Europe - if you have access to a Japanese account on either 360 or PSN the demo is definitely worth checking out.
