The standard is that usually, all console makers lose a chunk of cash on the hardware, but make up for it in software sales. Nintendo started this generation out by making a console that, against the norm, was cheap enough to manufacture that they could actually make money off the hardware sales. There aren't any official reports or charts or sales graphs to consult, because videogame companies don't usually release that sort of information. Hardware analysts figure out exactly how much each piece of the hardware would cost to manufacture and they create an estimate based on this. The videogames industry was generally under the belief that up until they dropped the GCN price to $100, Nintendo was actually making cash on hardware sales. Whether or not they're still making a profit at this lowest price is anyone's guess, but nobody has come forth to settle the argument one way or another.
