I am just curious - where are you getting the console costs from? From what I know this information is highly sensitive and even most insiders don't have an access.
Also, what scale do you use to compare costs? From the fact that you call Kinect (sold ~18M [1]) "one of the most popular consumer electronic devices in history" and Move (sold ~15M[2]) "has not taken off" it appears that either you are using some kind of highly non-linear measure or are better informed than almost everybody else.
I have no idea on the concrete numbers, but the two sources you cite appear to be separated by almost one year (jan/2012 for the Kinect and nov/2012 for the Move one)
Indeed, the sales figures are not synchronous. This is why I asked if GP has some special data, because the publically available one does not confirm his/her assertions.
The figures for the PS3 are well known. And the Wii/Wii-U's profitability per unit is also well known and publicly admitted. With any console you can generally just look at the parts list and compare costs to retail.
