Sony has a new message for Nintendo Wii gamers: Come join us. The Japanese maker of the PlayStation 3 unveiled Thursday its highly anticipated motion controlling system, as it takes aim at Nintendo's dominance in the gaming sector. With the “PlayStation Move,” Sony hopes to lure gamers who have outgrown Nintendo, which launched the Wii in 2006 and became the first to introduce motion-detecting controllers. Peter Dille, senior vice president of marketing for Sony Computer Entertainment, credited Nintendo Co. for “introducing motion gaming to the masses.” Now it's time for them to graduate to the PlayStation, which offers a new experience for both casual and hard-core gamers, he said at a press conference in San Francisco. Used with the existing PlayStation Eye camera, Sony's new wireless motion controller can track players' body movements. The controller, in turn, has on its end a light-emitting orb that is recognized by the camera. The PlayStation Move will go on sale this fall. Complete details of prices have not been released, but a starter bundle including the PlayStation Eye, motion controller and one game will retail for under $100, Dille said.
