Anyone check into this yet? The demo was released today in Japan, and its pretty fun. If you wanna check it out, create an Xbox live silver or playstation japanese account and download it, then switch back to your regular account. Very easy, as expected, but the boss battle with Kakashi is a good way to start it off.
I'm still amazed the game is about 50 chapters ahead of where the anime is now, and the game will have full english and japanese voice acting all the way through the Pain arc, and is including Minato/Sage Naruto/Akatsuki Sasuke, etc. Especially for the english voice actors since the anime only just finished the Hidan/Kakuzu arc iirc. Clearly its going to be packed with content, and if they make the game itself more like Broken Bond and keep the fighting like UNS, it'll definitely be a game to remember.
