someone claiming to be an employee of Kmart posted the new prices of the Elite and the Pro version of the xbox 360.

According to the picture (taken using a phone cam) comes September 7, 2008:

Elite = USD399
Pro 60GB = USD299.

However, no words on the Arcade version (which was rumored to receive a cut to just $199) - no stock

This is also inline with MS urging xbox 3600 drive makers to pump up their production volume - presumably anticipating a surge in xbox 360 sales
