Following the biggest shopping weekend of the year, Microsoft announced Monday that it has sold over 2.5 million Kinect sensors in less than one month of availability. Shortly after launch, Microsoft announced that it had sold over 1 million units in under two weeks. Thanks to the Black Friday shopping weekend, Microsoft has increased its sales pace since then — the highly anticipated motion-based controller is now selling approximately 107,000 units per day, up from 90,900 per day during its first 11 days of availability. While the numbers are quite impressive so far, this does make us wonder if Microsoft’s goal of selling 5 million units by the end of the year is looking a bit lofty right now. With less than a month until Christmas and the biggest shopping weekend of the year behind us, Microsoft is only half way there. If the company can somehow manage to keep up its current sales pace, however, Microsoft will smash its projections along with even the most generous analyst estimates.
