Microsoft scheduled a "Project Natal for Xbox 360 Experience" press conference at the E3 show in Los Angeles on June 13. But whether it's a formal announcement or just another explanation of the technology won't be known until then. At this year's Consumer Electronics Show (CES), Microsoft said that the Natal technology would ship by the 2010 holiday season. "As of now, we've only announced that Project Natal will be available holiday 2010, but don't have specific dates at this time," a Microsoft representative said via email. In the meantime, rival Sony has unveiled the PlayStation Move, a combination of a Nintendo Wii-like nunchuk and the PlayStation Eye camera.
