Kinect is outselling rival motion controller PlayStation Move by a ratio of 5:1 in North America, according to the latest NPD numbers.
That's according to everyone's favourite Wedbush Morgan analyst Michael Pachter, who reports in his latest note that over two thirds of Xbox 360 hardware sales last month were Kinect bundles.
"Under one-fifth of PS3 sales included bundles with Sony's Move controller, suggesting another modest month," he said.
"Over 2/3 of Xbox 360 sales included bundles with Microsoft's Kinect peripheral, as Xbox 360 Kinect console bundles again outsold PS3 Move console bundles by over 5:1. We note that the top selling Kinect software titles easily outsold their Move counterparts."
Last week Guinness World Records officially named Kinect the fastest selling consumer electronics device EVER, with the 360 motion cam having surpassed the 10 million mark worldwide.
Pachter say he can see the enthusiasm for the device persisting, with price cuts looming on the horizon.
"We expect demand for the Xbox 360 to remain stronger than the other consoles due to the popularity of Kinect," he added. "We expect Wii and PS3 hardware sales to continue to decline (despite February's up month for both) in the first part of 2011.
"Without further price cuts, we expect hardware sales to be down in 2011, and we think that the console manufacturers will position cuts around the E3 Expo in early June."
