Xbox360 版は北米版仕様を実装
Xbox360 版は、北米版『NO MORE HEROES』の流血・残酷表現を実装しており、
CERO レーティング「Z」を想定しています（11月16日現在、審査中です）。
北米版の演出を待ち望んでいた日本国内のゲームファンへ、強力に訴求可能です。

It says the 360 version will have blood and gores, and says it would satisfy the Japanese who wants to play the US version (Wii) and is rated CERO Z

Sooo, apparently the 360 version has gore and bloods, while the PS3 version will be like the Wii japanese version

All I wanna know is if the game will have support to the Sony's wiimote so it is worth checking.

yeah I guess that's the real question now....no info on that yet

Oh ?

that's weird, but also awesome since hopefully 360 version will be released in europe.

Where does the post says that PS3 version isn't rated Z?

I would hope not. Until there is a good solution to getting an analog stick with the PSWand then porting over a game that requires movement will be problematic. I'd be very surprised if they did not just use the default controller for both systems.

So i assume the version Ubisoft published in the West was bloodier than the Japanese version.

Well, the US version was the only one to feature blood, both the Japanese and PAL versions had black pixels and smoke instead.

Looks like the 360 version will be like the Wii US version and the PS3 one like the PAL/Japanese Wii version.

Well It only says that the 360 version is rated Z...no info on PS3 yet
