Shigeru Miyamoto has warned Nintendo's rivals have a tough road ahead when it comes to launching their new motion controllers.
"One of the challenges is not just to create a natural controller, but how do you get it into the hands of the people? How do you do that cost effectively?" he said, speaking to the Mercury News.
"I think we've accomplished that. We have sold millions of controllers at a good price point. And we have that delivery system successfully already implemented."
So Nintendo's got a head-start - but what about Microsoft and Sony? "For other companies starting from zero and trying to figure out how to get it out there at a decent price point is a big challenge," Miyamoto said.
Having mucked about with motion controllers for a while now, Nintendo has moved on to the Vitality Sensor. It was shown off by bossman Satoru Iwata at E3 but no one really understood what on Earth the point is, as it sounds like Miyamoto is aware.
"Ideally we would have been able to talk about this in terms of the software implementation rather than just the sensor itself," he said. "I don't have any indication for you (of what we have in the works) other than to say that we have lots of very creative ideas.
"We understand the challenge before us, and we have met these challenges in the past. We just ask that people have confidence in us."
Remember, every time you say the Wii Vitality Sensor looks rubbish a fairy dies.
