Okay lets see where to start 

1. This is bundles only, since the pseye already had a large install base many people would have just bought the wand and ps3 are far more reliable then 360s so people are less likely to need a replacement ps3 which would lower the amount of people buying a ps3/move bundled where the fear that their 360 might break down alone will cause several people to buy another 360 if they consider it a deal 

2. Pretty sure thats in the US only, I saw another article like this and it specified npd number, if we went with bundles in japan ps3 move is probably outselling kinect 10 to 1

3. That is assuming that a massive amount of ps move bundles are still on the shelf, which is based on nothing but patchers biased

4.it's also assuming that MSes 2.5 million sold to consumers is accurate, which again I don't buy without some source (360s number of sold to consumers has been higher then it was before and MS has shown the ability to skew results before (squaretrade report) 

so yeah, so it is probably true in the constraints that they put it in, but in those constraints it's meaningless, it's like saying that doesn't count 20 times to get the answer you want
