News that Microsoft lowered their estimates for how many Xbox 360s they'd ship before their fiscal year concludes in June emerged just after CES. The previously announced figure of 15M units was downgraded to 12M units. That's just two million units that the company plans to ship between January and June, considering that Microsoft met its goal of shipping 10M units (at CES, Robbie Bach announced that they'd shipped 10.4M units during 2006). Is Microsoft concerned with its shipment figures because two new consoles entered the market last fall? Or are they letting the retail channel sell through product before they announce the long and oft-rumored revised Xbox 360?
