Siliconera: "“This time, we used the 3D for presenting the game, but next time I want to make software that involves 3D in the game design,” Team Ninja leader, Yosuke Hayashi, recently said to Nintendo’s president, Satoru Iwata. “When I read Miyamoto-san’s interviews, I realized that he designs games that can only be accomplished in 3D. Like games that involve jumping into the distance.”
Another point Hayashi considers important while developing Nintendo 3DS games is to keep in mind the difference between a console and a portable system. Team Ninja are also planning a Ninja Gaiden title for the 3DS, which Hayashi tells us will be “appropriate for a portable system” when they decide to show it off."
