unsure of wii and previous nintendo consoles...
but all sony consoles have ben sold for less than manufacture price. i dont mean r+r + manufacture divided by console quantity.
i mean sony sell the console cheaper than what it costs them to make the console.
eventually the consoles become money makers too, but that is years and years down the track.
the big money for sony/microshit/nuntendo is in software. thats how they can sell their consoles cheaper than cost.
