Since November 2005, the Xbox 360 has sold more than 600,000 units in the US alone. Complaints of short supplies during the holiday season and a faulty power adapter did affect the final sales figures. Microsoft will attempt to meet consumer demand for this console by engaging a third manufacturer next month in an effort to ramp up production. The Redmond giant expects to sell between 4.5 and 5.5 million Xbox 360 consoles by June 30 this year.Via Reuters
