I actually tried the demo of this game, with my one friend who owns a PS3 (I was a big fan of the NES Ninja Gaidens, and quite good at them). My impressions were that the game was very pretty, very difficult, and extremely violent. I personally didn't care for it, but that was only a demo tryout - please don't refrain from buying this game on account of me! I actually couldn't stop laughing; for some reason, the absurdity of this game's plot (killing an endless succession of ninjas) was very amusing. I mean, the old Ninja Gaidens were just as bad, but the graphics were so unrealistic it made sense somehow. My mind couldn't fit the pretty visuals together with the B-grade kung-fu action, hehe. 
I'm very interested to see how the sales look this week. Can Ninja Gaiden hit 100k the first week in the US? That would be great news for the PS3, and certainly needed. We'll find out next week.
