We won't be seeing 200k weekly in the Americas, that's for sure. This week was probably a bit higher than most non-holiday weeks will turn out to be (God help the other consoles if it isn't!) It's probably more realistic that we'll see in the range of 300-350k weekly in the slow months of the year. That's an increase of 100k/week over last year, when the Wii very consistently did 200-250k every week during the spring, summer, and early fall.
The holidays will spike numbers upwards, and raise the average weekly sales over the 400k range. All told, we should definitely see over 20m Wiis sold this year. I predicted sales of 23m (for 42m lifetime) in 2008, and I'm pretty happy with my prediction thus far.
End of 2008 totals: Wii 42m, 360 24m, PS3 18.5m (made Jan. 4, 2008)
