According to Sony, the new controller couldn't provide the most value to gamers with a spring release, citing a fewer number of games that could use the new device.
"We have decided to release the Motion Controller in fall 2010 when we will be able to offer an exciting and varied line-up of software titles that will deliver the new entertainment experience to PS3 users," Kazuo Hirai, president of Sony Computer Entertainment, said in a statement.
Hirai went on to say that his company is working to build a "comprehensive portfolio of attractive and innovative games for the Motion Controller." Sony plans to unveil the software line-up for the new device "soon."
Sony's Motion Controller is designed to work with the PlayStation Eye camera. When those two devices are switched on, a gamer's hand movements are detected to allow them to interact with the action on-screen.
Sony isn't alone in its desire to bring motion gaming to the market after seeing Nintendo's success with its Wiimote. Microsoft's Project Natal, which is designed to recognize motion and eliminate a game controller altogether, is is set for release in the 2010 holiday-shopping season.
