From edge-online.com:

Natal will launch in the US this October with a price tag of $149.

That's according to a trusted source, who told us that the motion sensing camera will also be bundled with the Xbox 360 Arcade console for $299.

The figure for the standalone unit is significantly higher than a previous sub-£50 estimate, but less than pricing recently suggested by European retailers. It's also more expensive than Sony's Natal rival Move, which will be available later this year with a game for less than $100.

Our source said that the device has been pencilled in for an October 26 worldwide launch, although we were advised that the date could yet shift by a few weeks either way.
