5-5.1 million after post holiday adjustments. I think Europe and North America will have about 200k or more overtracked. Either way, it is very likely that the Wii U will end up below 3 million for the entire calendar year, less than half of the 360's first year and perhaps about 35% of the PS3's first year.
End of 2016 hardware sales:
Wii U: 15 million. PS4: 54 million. One: 30 million. 3DS: 64.8 million. PSVita: 15.2 million.
