According to a report issued by British games magazine MCV, Microsoft's much-heralded hands-free gaming control system could hit store shelves as soon as November and cost as little as $50.
MCV said that Microsoft could launch Natal with a 5 million unit global shipment.
"This and other details have emerged following a behind-closed-doors Microsoft tour of U.K. publishers and studios," MCV wrote. Microsoft "has been demoing the tech and detailing its 2010 plans in order to spur more development support."
MCV also said that it had been told by a publishing source that Microsoft is "trying to get as close as possible to 'impulse buy'" with Natal.
The technology is considered very important for Microsoft as it seeks to differentiate the Xbox from Sony's PlayStation 3 and Nintendo's Wii.
The Seattle Times weighed in on the story by predicting that, "This is probably a preview of what (Microsoft CEO) Steve Ballmer and (president of the entertainment and devices division) Robbie Bach will disclose at the Consumer Electronics Show in January."
Microsoft did not immediately respond to a request for comment.
