The current worldwide sales at this point is 6.68 million copies.

The game saw a 150k increase in week 5 due to Christmas weekend

I think the sales will still be strong throughout January

The game will probably see a 50k decline sales after the holiday season is over.

So my prediction for worldwide sales by the end of January 2010 is 8 million copies worldwide

I think the game's weekly worldwide sales throughout January will probably be somewhere between 750-800k

What are your predictions?

6.68 mil by Dec 19th... estimate 500K for Japan for the week of Dec 26th and you are predicting 8 mil WW at the end of January? I'm not sure how that works...

It will probably break 8 mil at the end of the year

It's already passed 8M, try again.

8.6mil if lucky

I am going to make a bold prediction, 10 million

me neither. It could do slightly less than 9m by Jan 1 2010, so tack on another .75-1.5m over the month, for 9.75-10.5m. (180-375k/week WW in January)

doesn't seem all that unreasonable considering how fast it is selling right now (300k others, 500k japan, 500k NA)

The numbers will be out on Thursday. probably that would be enough for NSMBWii to break 8 millions

He said end of Jan 2010 not end of 2009.

I wanted to say 10 million but I don't for sure. hey, it just prediction.
