Team Ninja's Yosuke "Itsygaki" Hayashi, director of Ninja Gaiden Sigma, told Pro-G that the development studio is not averse to developing a title for Wii, pending the title utilized Nintendo's more unique features. "We would make something for the Wii if we came up with something unique that would only work on the Wii," he said.
Given Ninja Gaiden's upcoming DS release and its unique control scheme, we can only imagine how Itagaki and co. would go about utilizing the Wii remote's pointer capabilities. Our curiosity turns into discomfort, however, when we think of Team Ninja making a Wii version of DOAX.
Hayashi further went on to describe the console preference demographic of the studio: "There are several groups within Team Ninja. The PS3 group, the Xbox 360 group, and there are Wii fans in Team Ninja." We've gone ahead and made a Venn diagram to help visualize the possible trichotomy.
