Sony's Move controller uses the PS Eye camera to track its distinctive glowing orb, and can also show a video feed on-screen. That, says Sony's Worldwide Studios VP Scott Rohde, is a "huge advantage" over Wii.
Rohde says Sony's not concerned about the seeming similarities between the Move games shown so far and existing Wii games.
"It's a homegrown technology and we chose it for a number of reasons - chiefly because of the precision that we knew we could get," he said.
"When you're talking about a game that was demoed like Table Tennis out there, you might be able to play that on another system, but I think we showed very well that you can get that top spin or slice in there and it really feels like you're playing a Table Tennis game."
And the added bonus? The camera. "Because of the camera, the PS Eye, we add that whole element of augmented reality. And I think that's a big advantage we have over what the Wii has done to date," added Rohde who says Wii owners will want to "upgrade" to PS3 when Move's released.
"That's definitely an audience that we're targeting ... Maybe someone is sitting on the fence about whether or not to upgrade [to PS3] and [Move] could lead them to do it."
Nintendo mouthpiece Reggie Fils-Aime said the firm was "flattered" by Sony's Move.
