Tecmo hasn't said much about the upcoming Ninja Gaiden Sigma for Playstation 3. Instead they're just teasing us with the following screenshots.

Ninja Gaiden is due out on Playstation 3 in Spring 2007.

It appears that Tecmo will first release the Ninja Gaiden sequel on the Xbox 360, since IGN quoted Itakagi that Team Ninja will "continue bringing out the newest releases on the Xbox platform before they're on other systems." We might see the Xbox 360 and Playstation 3 battle head to head, ninja style. Of course that's if the Playstation 3 is even out by Spring 2007. By out I mean with more than 100,000 systems.
