Well Nintendo said that they're selling Wii's for a profit straight away, so going by that, it wouldn't cost them as much to make as what they're selling it for. Unless it's only the Wii (as in, the console itself and nothing else that comes with the package) that they're selling for a profit.
I would assume it's the latter, because I highly doubt that such a complex piece of technology would cost less than $50 US to manufacture.
