You hear that, developers? You should be shakin' in yer boots -- motion-based gaming is going to force you to throw away everything you've ever learned about game design and start anew. At least that's what Lionhead's Peter Molyneux (not so exaggeratedly) had to say when quizzed on the subject of the "arms race" between the big three for waggle supremacy. "All of this stuff is making all the designers sweat -- I've met lots of designers at GDC, and we're all very bleary-eyed at the moment because every rule we've got, we're having to throw away," Molyneux told Eurogamer.

And understandably so. Between WIi's established console dominance (not to mention last year's MotionPlus add-on), this week's unveiling of PlayStation Move, and Microsoft's Project Natal this holiday, there's a lot to work with. It's this problem, though, that Molyneux believes will forge new types of game experiences in the years to come. "I don't think the first wave of these motion-control titles will be what you expect .... just as with every hardware chain, it's the second wave where they usually come up with stuff that's interesting ... so the second wave could be really cool."

And as far as Natal in Fable 3 goes, the eccentric developer kept mum on the specifics, only offering, "You can expect us to use Natal to make you laugh and to surprise you and to give you this feeling of power -- there are some very obvious things we could do, like controlling the GUI in Natal, and it doesn't really excite me." Tom Cruise will be so disappointed.
