Well after what happened to SMG, that's hard to predict...
I think, according to recent game sales, that Wii owners are not people buying games on first day or first week. That would be especially true for a pure casual game like Wii Fit. After all, remember the first weeks of brain training 1&2, english training, nintendogs...
The game releasing december 1st, It will probably benefit a little from christmas boost, though I expect it to sell more the following weeks when it's actually christmas.
With that in mind, my guess is :
First Day : 75K
First Week : 160K
Hardware Boost over previous week : +40K
