50 million is close to impossible unless Nintendo is really able to get those shipments out during the holidays. Otherwise 45 million is a more reasonable guess. Given inevitable increase in shipments it's probably that Wii at the end of October will be at around 38 million. Then the last 8 weeks, Wii will likely average anywhere between 750k-1 million a week. More than likely about 5-6 million in those 8 weeks which will put it around 43-44 million to end the year. This is the most likely trend given no bumps both positive and negative.
