I believe he's talking about "attach rate" - the magical metric that drives the console hardware industry (i.e., games purchased per console).

That's not such a magic number in this case. In most cases, console manufacturers make a loss on the console, and profit on the titles. Nintendo makes money on the console too, so it's not such an important figure.

Nintendo makes money on their hardware; the DS and the Wii were never sold under cost.

Sony definitely loses money on every console.

Don't know about MS.

IIRC, the PS3 slim is profitable. The PS2 has also been profitable and has been a consistently good seller (with some decrease in late 2009 and early 2010 (but that's expected - the PS2 is old). Console death rate is also a problem: even if it's not replaced under warranty, it's still a loss for the 360.

I also have a Wii ... it's just lying there. I just don't like it ... once you get passed the initial "wow" when trying out that controller, the games are pretty shallow and it is not capable enough to at least dazzle me with beautiful graphics.

Should really subtract out the 63M for Wii Sports though.
