Additonal Info:
Today, Yosuke Hayashi, the Ninja Gaiden Sigma director, revealed at the Tecmo's Nite Out 07 conference that Team Ninja has completed development of Ninja Gaiden Sigma.
"We just finished development recently," Hayashi stated. He also revealed the release dates of the game for Japan and North America. It will be launched in Japan on 14th June and in North America on 3rd July.
Hayashi didn't reveal the European release date, since this is in the hands of Eidos, who recently stated that the title would be available in Europe this summer.
Along with the Ninja Gaiden Sigma announcements, the president of Tecmo, Yasuda, revealed that they will establish a new development team at the beginning of this month. The new development team will be called "Team Tachyon".
Yasuda explained that tachyons move at the speed of light, and with this name, Tecmo intends to break that speed limit (whatever that means).
Stay tuned for more news on Ninja Gaiden Sigma and the new development team.
