I think there's something everyone's overlooking: the market grows with every year. Logically, each generation has a better chance of selling x amount of consoles because the market is bigger. I'm going with yes, but not by a gargantuan amount. I'll estimate 130mil total.

I dunno. I bought 3 PS2s, and I can't imagine the Wii being that crappily made. So I'll say no.

YES, WHEN INITIATE THE OFICIAL WII SALES IN CHINA , INDIA AND PAKISTAN
THE WII SALES, OVERPASS THE HISTORY OF PS2, IN NO MORE OF 3 YEARS

It's 9 months since launch and it's sold more than the PS2 did in its first 9 months.

I think we've only seen the beginning. Nintendo by far has the upper hand in the price war and Microsoft and Sony's advantage, graphical capability, is being hamstringed by slow HD adoption. They're already making a profit on each unit and they have economies of scale on their side. It may be years before Wii sales are demand limited since Nintendo should be able to lower the price every time demand goes lower than supply.

I predict that by the end of this generation, nearly every console gamer, except for the most stubborn Xbox and Playstation diehards, will own a Wii. Some of them will be a bit reluctant to buy it, but by the time it gets down to $150, there's going to be enough must-have games that it will be nearly impossible to resist.

No.

It won't be available on the market long enough to do that before the next Nintendo console comes out.

Given that it has stronger competition than PS2 did, I am going to also say no. DS has a strong chance if it is not replaced in the next few years however.

Yes

It is the fastest selling system ever. Sales will continue to go up just ass the PS2 did. If the PS2 sold at it's current rate after 9 months, it wouldn't have sold as much as it did.
