While Sony shipped one million PlayStation Move controllers to retailers in North and Latin America in the peripheral's first 30 days on sale, consumer adoption has been much slower than expected, according to Wedbush analyst Michael Pachter.
He said in a research note that "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," Pachter wrote.
"Interestingly, the higher priced Kinect controller appears to have overtaken the Move controller in the sales race."
Move seems to have performed better in Europe, with Sony claiming "somewhere in the region of 1.5 million" sales in its first month on the market.
Microsoft said yesterday that Kinect sold one million units globally in its first ten days of availability.
