Maybe I'll actually be able to see Wii Fit on Friday.

Hmm, I wouldn't go as far as saying world wide but in the us yes

I meant in world  total, not regionally separated.

FishyJoe, what's your estimate then, for Wii Fit's sold during Black Friday week in NA?

By adding around 180k to that (reasonable Others + Japan figures), you get the WW total.

What are the contenders? Any big releases this week?

It's kind of pointless to give a number, since I don't have any idea how big the stock pile is. It will sell as much as is stock piled.

All the big releases are out except Animal Crossing. But those buyers are not the same as Wii Fit buyers.

it will sell at least one copy

yeah that's very possible ,what's it's biggest competitor? I'm guessing MarioKart could come close but I really don't see much competition

I highly doubt this..but who knows, a lot of (not all) Wii owners like to buy things they use for a few weeks and never again..so it might. I really doubt this though.

WW Software Sales for Black Friday week: (across all platforms)
1) WiiSports
2) WiiFit
3) MK Wii
4) Wii Play
5) Animal Crossing

A bold prediction indeed.
