The third tier version of Microsoft's Xbox 360 gaming console went on sale in North American stores yesterday. The updated version of the original Xbox 360 comes in black, along with a new 120GB hard drive and a high-definition multimedia interface (HDMI) output. The Xbox 360 Elite console is currently available with an estimated price of $479, which is $80 more than the 20GB version. Unlike the launch of the PS3 and Wii, the Xbox 360 Elite should not be too difficult to find stocked on store shelves in the days following its debut. The new detachable 120GB hard drive will also be available separately for an estimated retail price of $179.99.
