While launch details are still a big secret for Sony's motion controller for the PlayStation 3 console, one thing has been revealed - the codename for the device.

EA's CEO John Riccitiello has let slip that Sony has been referring to the motion-sensing accessory as the "Gem".

At a media conference in New York this week, Riccitiello said, as part of a wider speech: "Natal [Microsoft's motion sensing game solution] and Gem, these are likely to bring new consumers into the marketplace".

"We haven't announced a final name at this point", Sony Computer Entertainment of America director of comms has since told gaming blog Kotaku, before stating "Gem" was in fact "an early code name for the product".

Sony debuted its magic-wand motion controller at E3. It works with the PlayStation Eye camera and claims to offer image recognition, depth detection, and gyros for a more interactive gaming experience.

Whether or not it keeps that name, the Gem system is due to be available to consumers in spring 2010 - we will keep you posted.
