Im fairly sure Wii will be less than $200 when it ships.
I have read a few financial reports online, and it seems that given the hardware in the Wii, it should cost Nintendo no more than $150 to build and ship a Wii. If this is right, and they charge $249.99, that would be a profit margin of 60% which is unheard of in consumer electronics, much less video game hardware which is either sold at a paper thin margin, or at a loss to get it into homes so they can start selling software, which is where the real money is at. That being said, Nintendo normaly does not sell hardware at a loss, so if I were to guess $199 would be a more likely strategy. Though if that aprox $150 figure is true, it could be even less, maybe $179 by time they ship, I seriously doubt it will be as much as $249 given what I have read. I just dont think Nintendo is ready to show their full set of cards to Microsoft and Sony just yet.
