They could do it, if largest market share was nintendo's goal over profitability. If they were to cut the price of the Wii by $100, and bundled in Wii fit with the console in addition to Wii sports, and upped production to 2 million a month, and started working on new things like Wii fit to attract causals, and worked on making a really good RPG/Multiplayer FPS ect the Wii could reach 240 million quite easily. I doubt Nintendo will do it though.
