Its actually performing rather similarly to Wii Fit if you align the numbers (Wii Fit launched in Japan in Dec 2007, vs. spring 2008 in the West) on a worldwide basis. That comparison strikes me as more valid since both were effectively new controllers bundled with a game to an existing base. Wii Fit did about 2.6m in three weeks. Its still not a perfect comparison, as Wii Fit sold to a smaller base in 2007-2008 than X360 has now, and costs less than Kinect. Wii Fit's 2.6m was also 3 wks in Americas / Others / Japan while Kinect's 2.5m is 25 days in the USA, and less than that in Europe and Japan. But I'd say the price (in favor of strong performance on X360) / base (in favor of strong performance of Wii) and regional differences (21 days in three equal regions vs. 25 days in strongest region and less time in weaker regions for kinect) just about offset each other.
It really is rather similar to Wii Fit...but launched over Christmas.
