While video game sales are generally down, the XBox 360 has been enjoying the extra sales. These are probably attributed to the Kinect system bringing in a lot of new customers. They sold so much in December that they ran out and had to eat into the production of January and February.
In order to make those numbers happen, Microsoft said it made available units from its January and February production runs. “Despite this, Microsoft still experienced out of supply situations in late December, and it expects supply constraint to continue in January and February as it works with retail and manufacturing partners to expedite production and shipments to replenish the channel,” a Microsoft spokesperson said in a statement, confirming news of the shortages from earlier in the day.
