Yes I did steal the idea from the source. =P

Personally

Wii -170Mil - if Ninty has truly found a blue ocean its is possible, personally I consider this number to be highly unlikely - but possible.

PS3 - 100Mil - The PS3 simply cannot beat the PS2 its price will not reach the sweet spot soon enough, possibly hitting the $200 mark bordering on the next gen. This number would require a massive slow down for the Wii as has been predicted by some people.

X360 - 100Mil - Basically doing the same thing as the PS3 but bigger due to the lower price (will hit the $200 sooner) but also without Japan. Also ruling America in an all American way.

Wii - 250Mil - If blue ocean and all major markets see a healthy increase in total console sales, and major sales increase in underdeveloped markets such as China (not easy for a console because of piracy and other problems, but Nintendo has the best shot) and they get the price down

Well I put these in TheSource's thread but I will put them here too, by the end of 2011 (more sales in 2012 and 2013) which is basically the bulk of this gen sales I think:

Wii: 90-100 million

360: 50-60 million

PS3: 60-70 million

250million for any console sounds waaaay too high....anyway,when all is said and done,I think all 3 will pull very respectable numbers worldwide.

PS3: Stunted growth. If it sells well, it won't be until 2009, which means... let's say they average 5 million/year for the first three years, and then an average of 15 million the following three. At peak, that would put them at 60 million

Wii: Well, let's say sales are completely constricted by supply... let's say they average 2.5 million consoles/month, and let's say things stay there... if everything goes right (and I mean EVERYTHING), let's call it 190 million.

X360: OK, Halo 3 shoots the console up hugely, and they end up with 20 million by January '08. Let's say an average 15 million for every following year, and you'd end up with a total of 80 million.

(all estimates assume a 6-year lifetime)

best case? hard to predict, i even can`t predict will ps2 sell only 120 mln. or 150 mln. worldwide? =))

PS3: 70-80 million

360: 70-80 million

Wii: Extremely hard to predict. Frankly, I'm waiting to see how big this blue ocean they've tapped in to is. Is this "casual market" 10 million people strong? If so, then I'd say 70-80 million. But what if people's parents start buying it in droves? What if there is 30 million? 40? We really don't know yet, so I personally don't think absurdly high figures are totally out of the question.

I'll say 150 million. I'm not saying this is likely -- it simply represents my position on the blue ocean. It's possible this ocean is really, really big.  

Wii 95-105 millon
360 45-55 ""
PS3 35-45 ""

Wii:100M
Ps3:90M
360:80M

Wii: 130M
