Wedbush’s Michael Pachter says under one-fifth of PS3 sales included Sony’s motion-controller–while two-thirds of Xbox 360 sales included its camera-based system.

Yesterday, the NPD Group released its sales figures for the month of February. Though the research group no longer releases hardware sales numbers, Microsoft was all too happy to announce the Xbox 360 had sold 535,000 units during the month. Sony did not release sales figures, but, in a note to investors, Wedbush analyst Michael Pachter revealed the company’s console sold 403,000 units–51,000 units less than Nintendo’s Wii.

Kinect is outselling the Move 5-to-1 in bundle form, says Michael Pachter.

While enlightening, the console sales aren’t the whole story. According to Pachter, over two-thirds of all Xbox 360 sales–or at least 358,000 units–were bundled with its Kinect motion-sensing system.

By contrast, the analyst says under one-fifth–or less than 80,000 units–of PlayStation 3 sales were bundled with the Move controller, meaning Kinect outsold it by a ratio of nearly five-to-one. Pachter did not mention standalone accessory sales.

Indeed, Kinect has proven a major success for Microsoft, shipping over 10 million units worldwide as of this week. How the PlayStation Move has fared is less clear.

In late November 2010, Sony announced that some 4.1 million Move controllers had shipped since they went on sale in September.

However, since the Move system incorporates the PlayStation Eye–which has been available since 2007–it is unclear how many complete Move systems have been purchased.
