As a designer it's "another one of those things" he'd love to "play around with." Platform holders "make the hardware," it's really up to studios.
"I have seen some of it. We're not really surprised, are we? I mean at E3 last year we saw they were having a wand, and that's kind of what I expected," Molyneux told Eurogamer in an interview at GDC.
"It looks like they've taken a step forward but it's not as big a step as something like Natal, I don't think," he said. "This is purely me talking personally, but I think maybe it's slightly more a device for the core than it is for the casual market, because I think it's quite precise."
"As a designer it's another one of those things I'd love to get my hands on and to play around with. As a consumer, everyone's talking about motion control now - I mean, I'm starting to get confused. It's kind of like the arms race, with the Wii MotionPlus and now the Sony Move and now I'm getting kind of confused."
Asked what he thought of Move in relation to Natal, he said it's "down to what us poor old designers do with this stuff, because all these guys do is make the hardware".
"Whether we utilise that hardware in a real way or whether we just take shortcuts, that's really going to be where we succeed or not." There you are - the success or failure of Move and Natal isn't down to Sony or Microsoft but the studios behind the games.
Fable III got a larger revealing at GDC, with a job ad recently giving credence to a PC version being in the works at Lionhead Studios - supporting cross-platform play?
