If priced too high (399$/€ or more), WiiU will hardly be a threat to Wii's sales. In that case, Wii should remain high during the holidays and break 100m, but WiiU's milestones will be a struggle... 

i love how you generalise the attitude shown in the op of a thread made by 1 individual to millions of other people

Although it's clear Nintendo sort of left the Wii out to dry with its lack of games these past couple years, I think the third party developers have to share in the blame as well for cutting the lifespan short. Wii will probably reach 110 million when it's all said and done, but if only it had better third party support, I believe the console could have put up PS2 like numbers.

It'll stop between 110 and 115 as it continues to be produced at a profit for Nintendo over then next 3 years, especially considering it still needs to be bottomed out at the $99 price point.

Your argument is based on the assuption that the Wii will nearly completely stop selling after the Wii U releases, and it's wrong for two reasons:

1. There's still time before Wii U releases. Like most Nintendo consoles, Wii U will be most likely released by the end of the year or near it. At the earliest, I'd peg September, so that still leaves 6 months for the Wii to continue selling. In America, the Last Story, Xenoblade and Mario Party 9 are still about to released and in Europe, there's still Pandora's Tower and also MP9 coming. So with enough momentum and a pricecut, Wii might reach 100million even this year.

2. You really think that all families, all retirement homes, all children will suddenly migrate to Wii U? Hell no, people will still buy Wiis, especially if the price will be tempting. Right now, the prices range from $139 to $169, think of what will happen if they drop below 100 bucks. And I'm pretty sure Ninty will drop the prices to clear out the storages.

It will reach 100m for sure, I'm willing to bet.

You are meaning to say that the Wii's sales during December 2011 will be approximately equal to it's sales from March 2012 until it is taken off the market?

Bullshit. It will be at 100 million by the 25th of December 2012.

People saying dropping the price of Wii will get it across the line. Wii doesn't quite sell itself it still needs advertising. what will Wii's advertising budget be one month out from Wii U launching? Not much. And after Wii U launches it'll be less than that.

PS2's price drop to $99 did very little for its sales, I don't think a Wii drop to $99 post Wii U launch will do much.

I think Wii will have about 2.4 million units left to get to 100 million by the start of November. ~ 8 week, 300K per week average. I think If Wii does that it will mean Wii U not selling as well as Ninty would be wanting. Still if it doesn't make 100 million this year it will certainly get close enough that it will limp across the line before it's officially taken off the market.

Interesting that people said tech doesn't matter for sales, but it does matter for longevity. If Wii had tech on par with PS3 / 360 then it would still be capable of making a run at PS2's record. The again would Wii with tech similar to PS3 / 360 have the sales it does today? Possibly not.

Yup. I don't know why they killed off the DS so early when it was still selling really well.

Just look at the 3DS launch. It was a mess. Why did they rush it? They could have easily waited until the holidays and avoided that early price cut. They could have sold millions more at $250 during the holidays then cut it to $180 in the summer if necessary.

Wii was bound to struggle in its late years. They really didn't future-proof that console at all. The sad thing is that it looks like they are repeating the same strategy with the Wii U.....

Lack of 3rd party support is Nintendos fault. They made an under-powered console which made it very hard to port over HD games to the Wii.
