Robot Magazine: http://botmag.com/articles/lego_mindstorms_robot_news_1.shtml Not much technical detail but have pictures and video of 3 other models. From the Developer Program page, the new unit still use 6 AA battery: http://mindstorms.lego.com/press/LEGO%20MINDSTORMS%20Issues%20Call%20for%20NXT%20Great%20Developers.aspx

And USB is powered, right? Is there any reason not to use that source? Forget the USB-powered coffee mug hotplate -- I want to run my MINDSTORMS on USB! Steve

But it’s got USB. And USB is powered, right? Is there any reason not to use that source?

Powered USB port can deliver up to 5V and 500mA, so that is insufficent for LEGO motors.

This would depend on how much of its USB stack is implemented in hardware DSPs, or how much is simply Firmware. Then adding a 9v powered hub and some USB based IO makes it hugely extensible. Again - going back round to the PC powering the NXT as a device, it could mean for a very large bot, you could add a larger battery and power the NXT from it. -- Danny Staple MBCS OrionRobots http://orionrobots.co.uk (Full contact details available through website)
