Ah I like how people are analyzing my predictions lol, but each of them can and will happen, we have only seen the tip of the Wii iceberg my friends, Wii has yet to do any of the things that ignite sales, no price cuts, its still above $199, most PS2's 80% were sold at below $200, in addition Wii is availible in only one color, as we have seen with the DS different color schemes are very popular. We have yet to see the true demand of the Wii.

Nintendo will be forced to up production beyond 2.5 million per month this year, probably up to 2.5-2.7 by the end of the year, and will go beyond 3.0 in its third year (possibly as high as 3.5), while I don't believe it will sell 40 million this year, I expect it to surpass 80 million in sales in 2009 and 2010 combined.

As for my other predictions, my 2008 ones are very likely as is my 2015 one, and as for Wii fit, I expect that to be very likely since I expect Nintendo to announce at E3 a full range of Wii fit games which use the balance board, think about it, things like Wii tai chi, and Wii yoga and Wii cardio, etc.

Many of you people are seriously overestimating the console market. Not even handhelds with ultra-broad demographics and half the price sell that quickly.
No one can deny at this point that the Wii is selling very well, and I'll readily admit that I underestimated it in it's first year.
I do, however, think that it's extremely overestimated here on Vgchartz, no other site in the world is this optimistic about it, including Nintendo's own fansites.
At least try to be realistic, only a very small percentage of the predictions made here will come true (mine are just as lilkely to fail).
And stop pretending to be a psychic Avinash and respect other people's opinion, you really don't know how to respect anyone in here.
No matter how idiotic some things sound to you, let people think what they want, just like most people let you think what you want. It's common decency, even on the internet.

No other site is the most comprehensive sales site in the world Mummel

I understand certain people here are being optimistic but you are claiming that the wii will hit about 50% of the ps2's sales in just over 2 years. simply not realistic..

I find Mr Tyagis predictions to be an odd mix of ridiculously impossible & completely likley... "Sales of Wii Fit will surpass the combined sales of the Grand Theft Auto franchise" Based on what?!! Insane prediction. "Lifetime sales of Wii will surpass the combined sales of the entire Playstation family of consoles by 12/31/2015" This is completely ridiculous. You just havnt thought this through. By 2015 the PS family could VERY EASILY be around 350 million. The chances of the Wii selling 330+ million units in the next 8 years is not high. I know its supply constrained but currently the Wii isnt really outselling the PS family week to week. Last week the PS family sold 264,000, the Wii sold 224,000. The week before the PS sold 502,000, the Wii 561,000. So a 60,000 unit weekly advantage is going to equal 330million in 8 years somehow? The Wii would have to OUTSELL the PS family by 37 MILLION(!!!) per year, starting from now. Yes you read that right, 37 million per year!!! "Wii hardware sales will surpass the total hardware sales of the PS2 by 12/31/2010" This is possibly even more ridiculous. The PS2 is still shifting a lot of units, this is just NOT going to happen. "Wii will have 50% marketshare or more by the end of 2008" Yup probably. "Wii will surpass 45 Million in lifetime sales by the end of 2008" This is almost definate. Barring asteroid strike, this is guarenteed to happen.

Just to throw a thought into this ring:

Look at Wii sales for the start of '07. They slowed a lot, then exploded after March was over. Why?

Nintendo's fiscal prediction - they will dry up supply of the Wii (esp. during March), to hit their predicted sales figures spot on - upp them for the next financial year - then release a lot more units starting April '08.

...

So I wouldn't extrapolate Wii sales for this coming year too heavily based on the coming 3 months. Wait till after March, and see Ninty's fiscal statement for '08-'09.

(that said, I don't see any chance the Wii will outsell the Playstation family lifetime - not in the next 5-10 years anyway - unless Sony decide to fold now!). 

 Not even close, the PS family (PS1, 2 and 3) are currently topping out at 227 million consoles sold, you really expect they will add 123 million consoles in eight years, not a chance, the PS3 will be lucky to sell even 30 million more, and the PS2 will top out at maybe 10 million more sold maximum, meaining the PS family of consoles will be under 300 million in eight years, even accepting a PS4, in order to reach that level Wii will need to sell a little more than 30 million a year, probably around 31 million a year will do it, which is doable

The PS2 isn't shifting enough units as it was and is in decline, another year of good sales is what we can expect, probably around 120 million maximum, in order to break past that by the end of 2010, Wii would need to sell about 34 million a year for the next few years, again doable

 Wii fit passing the GTA family is based on long run legs and attach rates,  basically an attach rate of about 35% for Wii fit would be enough to net the needed sales to pass the GTA family.

60 million by the 3rd week of jan 2009?......... ;-p

And that is probably the most important factor to consider right now, making any predictions based upon current (mid Jan - Mar) sales somewhat incomplete from the standpoint that they would be using skewed numbers.

That was the only conclusion I came up with when last week's sales figures came in. I expected a significant drop off, but not that much. It looks as though the number of Wii's sold this month will be well under the current production rate of 1.8m. That is unless this week's total is in the range of 600k or more and the final week of January is around 400k. But a drop off would be consistent with last year.

What isn't too clear is how Nintendo can make a projection of max sustainable sales through 2008 for the purposes of production if they continue to restrict distribution at current production rates. That is unless they aren't trying to predict max sales for the purpose of saturating the market, but rather sustainable sales at reliable/predictable rates (to move 100% inventory).

The most likely explanation is that they've already planned two conservative, slight increases in monthly production to 2.0m and 2.2m starting in March and later in June or July. That is pending the hit of their sales estimates through Jan-Feb and subsequent fiscal projection for Mar 08 - Mar 09.

That would yield annual production of about 25m (44m total by year end 2008), not factoring in for the exact date when production increases. Based on Mar-2.0m and Jun-2.2m.

There's always the possibility Nintendo will go uncharacteristically aggressive in their projections and production rates, but Nintendo is a very conservative company.

 Well what made them conservative was the GCN failure, I think Iwata stated that they were going to increase production this year a little more agressively
