NoA boss Reggie Fils-Aime has told Kotaku that Nintendo would have been "embarrassed" to be part of Microsoft and Sony's catch-up to motion gaming.
"I think a hallmark of Nintendo is that we are constantly trying to innovate," he said, speaking in the wake of Sony's Move reveal at GDC this week.
"I think we would have been embarrassed to do what our competitors are currently doing.
"So, all I can tell you is that we will innovate. We will provide something new. Something that the consumer and the industry will look at and say 'Wow, I didn't see that coming.'"
Fils-Aime reiterated Nintendo's refusal to come to market with new hardware until Wii has nothing left to give.
"When Mr Miyamoto goes to Mr Iwata say, 'I have this great idea and I can't do it on the Wii,' that's when there will be a next generation console," he said.
"What that includes we'll see. I think Mr Miyamoto himself has said that he is very interested in a high-definition experience, but to be 120 percent crystal clear, HD by itself in our view is not enough to go for a new console past the Wii."
Lots more through there. Move and Natal ship later this year.
