The demo of Ninja Blade is hitting XBLM on December 29 in Japan. No news on whether the demo will hit anywhere else.
After a full month, January 29th, the full game will be releasing in Japan, while no words other then TBA on other regions.
Considering it's from the same people involved with Tenchu 4, we can probably assume this game will be very good.

This should settle your curious nerves. From Software has announced that they will be releasing a demo for their new ninja title, Ninja Blade, on the XBL Marketplace come December 29th. What you have to note, though, is that this is for the Japan XBLM. But we're sure that won't be too much of a hindrance to you guys. We know you'll always find a way, right? *wink, wink*

Anyhow, Ninja Blade, for those of you curious enough but too lazy to find out more about it, is in fact, a so-called "Cinematic action game". Heavy Rain comes to mind. It's also said to have hack and slash elements, coupled with context sensitive commands. Hmmm... interesting, innit?
