Sony's PlayStation Motion Controller now codenamed Sphere?

Sony may still have officially been using the less-than-imaginative "Motion Controller" name for its, um, motion controller at the Tokyo Game Show last month, but it looks like some developers working with the technology weren't sticking as close to the script, and may have revealed the project's proper codename. As Joystiq notes, Sega producer Yasuhito Baba referred to the device as "Sphere" during an interview at the show, and Polyphony Digital's Kazunori Yamauchi also seemed to respond to the "Sphere" name without missing a beat when asked if Gran Turismo would support the peripheral. So, certainly less of a mouthful, and not exactly the worst of names if true -- in fact, it's such a good codename that none other than Microsoft has already adopted it for one of its projects.
