So Nintendo was the only manufacturer who did not apply the "razorblade" model of the other console makers, which is understandable since they were and are a videogame company only and thus never had any other branches which could have been able to subsidize their console business in the beginning (unlike for example Microsoft).
I think the first console Nintendo made that actually sold at a loss is the current 3DS handheld and that may be after the very fast initial price cut after the slow reception on the market.
Nintendo, meanwhile, couldn't keep Wii in stock for more than half a day until something like 2 years after launch, so they could have raised the price about $100 and not lost a sale
