How to Make 10 Million Sound Like an Unimpressive Number

At GDC, Sony engineer Gabe Ahn proclaimed that 10 million PlayStation Move units have been shipped to retailers since the motion-control system was released in late 2010.

Yeah, that's "shipped," not necessarily "sold," but we can infer a decent portion of them have at least cleared shelves. Of course, included in that total is the PlayStation Move Navigation Controller, which is basically useless with a move game, except to provide a more ergonomic secondary control and a means of going through menus and selecting options.

Ahn said the figures showed an attachment rate of 1 out of every 6 PS3 owners buying a Move controller. I'm not sure why one of them would buy a Navi controller and not a Move wand. I'm sure many bought both, and still others bought two Move wands and a navi controller. Ten million sounds good next to the 18 million Kinect is reporting, but Kinect is a single device.
