With US researcher NPD Group keeping a tight lid on sales information these days we have to be satisfied with the crumbs of information that makes it way out to the general public. Thankfully, people like Michael Pachter get the full information and he likes to make a bit of noise. CVG quotes Pachter saying the following about Move sales.
"Move sold well below expectations in its first month" in the US, and NPD sales results for October suggest a "modest second month" performance.
"We estimate that Move has sold through approximately 400,000 units in the US in its first six weeks on the market."
"Interestingly, the higher priced Kinect controller appears to have overtaken the Move controller in the sales race."
In Europe Sony have shipped 1.5 million units of Move and demand appears higher.
