I'm sure he didn't make a mistake on this, they are profitting on each. With how precise the pricing is on parts, sometimes the profit margin is very small, especially once you cut in the retailers. It wouldn't surprise me if their profit margin was a fraction of a percent.Also, while both MS and Sony sold their previous consoles at a loss, Wii did not, and none of the consoles now available do (as far as I'm aware). Before then, I don't remember anybody caring, though I'm sure it happened. All things considered, I certainly wouldn't say it's a common place idea now, and I don't suspect it will be in the future, considering how this console generation is going while all the companies are selling for profit.
