Details have emerged regarding Microsoft's closely guarded Project Natal motion gaming add-on for its Xbox 360 games console.

While all we previously really knew was that the system would hit the shelves during 2010, games site MCV has heard from industry sources that November 2010 - so in time for Christmas - is the worldwide launch timescale.

In addition, information from a "behind-closed-doors Microsoft tour of UK publishers and studios" suggests the Project Natal add-on will cost "under £50" when sold as a standalone device, with one source even suggesting a £30 price point.

Other snippets leaked from the meeting suggest Microsoft is planning to manufacture 5 million units for the launch and that 14 games will support the motion-controlled device as it debuts.

We will keep you posted.
