around 45 million is my prediction.

I'm actually going to change my prediction to:

Low: 42.6

High: 44.6

As I didn't account for increases leading up to the holiday.

Yes, but US parents might pick up their kids an Xbox 360 since it is now $50 cheaper during a bad economy.

40 million is a given, I predict 42-44 million.

I think that the Wii will be huge in Europe this holiday season with Wii Fit and Mario Kart, so I'd say it could easily make 40 million.

41M is a very low ball number around 42-44 have average in that range Wii willl do ve3ery nicey compared to last year.

the real question could be : Can it pass 45 mil by December 31?

 Now THAT would be impressive--I think there's a slim chance.

Wii will EASILY hit 40m by the end of the year. Nintendo's financials have them shipping 51m by the end of March 2009. So unless you expect a completely insane Q1 of next year, Nintendo should reach 44-45m sold in 2008.

I'd say 42 million absolute minimum. I have no idea how it will sell in the weeks leading up to Christmas, but I'd say 44-47 million is definitely possible.
