When will Wii outsell PS1 though? (102 Million) late 2011 I think.

In another 6 years, if Nintendo keeps on selling it so long, it would be easy. In another 5 years if its late years sales drop is small enough (and this could happen even more easily if Nintendo releases Wii2 late). In less than another 5 years it's quite difficult, not impossible, but hard.
Anyhow, Sony will keep on selling PS2 as long as sales hold, to make it as hard as possible for Nintendo, PS2 image is important.

Think of it this way, if it stays on the market as the leading nintendo console for another 4 years and sells at least 17.5mil a year (that's 70mil in 4 years), then it will outsell the Ps2. I think that it will accomplish that if there isn't a wii 2 or whatever they'll call it.

2014

DO NOT OPEN PANDORA'S BOX!!!!

:P

This has been hotly debated on VGChartz for years, but I think the error is that for part of the PS2's life, Sony reported manufactured units as shipped. Ie 8 million people had the PS2's replaced under warranty while this reporting method was used. Sony changed to reporting shipped units when they arrived at the retailer's warehouses some time before the PSP launch

I could be wrong, if you want to know more start a thread on it

If the Wii had as long of a life as PS2, it will outsell it. However, I think the Wii 2 will be out before that day so I think it will never happen IMO.

The PS2 was not killed off by the PS3(or the Wii), why would the Wii be killed off by the Wii2 (or any other console)? 

Good point! However, the reason Wii will die after Wii 2 is because Nintendo will move to Wii 2 in game productions. Without Nintendo games, the Wii will not survive. The PS2 can live without Sony games.

never, I don't think nintendo is smart enough to keep the wii on the market that long,when they upgrade..... and they will upgrade, they will drop the wii as fast as they did the gamecube imo, it can though..... only if it stay's on the market long enough like 5-6 mmore years.

That is a good point also, although don't let the Sony fanboys hear you saying the Nintendo first parties are more significant than the Sony ones :P I suspect however, that the huge lead Nintendo has (launches aligned) will be more than enough to offset the effects of the Wii2 releasing earlier (although in all likelihood it'll only be 6 months earlier) and the fact that the Wii relies on its 1st party more.

And hollywood - this is a multinational corporation that has managed to dominate 3 of the 5 generations of home console it's been in, and all of the portable generations. They have some quite clever people there. The NES had a lifespan of over 20 years, and the SNES about 13-14 if I remember correctly
