Epic's Cliff Bleszinski has said he finds motion controllers "very interesting" but favours those like Natal which don't rely on any hand-held controller.
"I find motion control to be very interesting, very compelling," he told IGN. "The ones that I personally like the most are the ones that are more natal-like; that don't have yet another plastic controller sitting underneath my coffee table cluttering everything up. That I can just fire it up and do very cool movements and have interesting results."
He continued: "As a side note, the kind of game that I think will be the most interesting will be something that's a hybrid."
"Maybe it's something where I'm playing the game with a controller and your significant other can sit there on the sofa and do gesture based things... So that you bring the hardcore and the casual together in a compelling fashion
