Shigeru Miyamoto had already claimed in one E3 interview that Nintendo's years of experience with Wii give it the edge on motion control, but it turns out he also told Wired that he believes a physical controller is still vital.
"As someone who thinks of things from the perspective of creating interactive experiences, I really think that you do need something," he said.
"I don't think as a creator that I could create an experience that truly feels interactive if you don't have something to hold in your hand, if you don't have something like force feedback that you can feel from the controller."
That's obviously in response to Microsoft's Project Natal, which employs cunning custom hardware to measure your movements and recognise your voice without the need for a pad or wand.
Sony also announced a motion control system at E3, which uses EyeToy in combination with a pair of wands with lights on to register gesture movement, and Miyamoto implied that this was because Sony, like Nintendo, believed force feedback was necessary.
He also made a similar point to the one he made with the BBC: "Looking at what the other companies have shown here at E3, it feels like they have finally obtained the very basic technology for doing motion control, but perhaps they still have to learn how to use that and take advantage of it in an interactive experience."
