My guess for each console is.

Wii 110m      new console in 2012

xbox360 60m     new console in 2011

ps3 80m       new console in 2014

Im sure that there will be a new xbox console in 2 years, a new nintendo in 3 years and a new playstation in 5years.

what do u guys think?

Wii- 120-130 Million

360- 60-70 Million

PS3- 70-80 Million

Wii 110-120 million

Ps3 80-90 million

Xbox 360 60-70 million

Wii: 100-110M

Playstation3 49M

Xbox360 50M

I expect the PS3 to begin catching up to the 360 when the gen is about to end, and just before it surpasses it, both systems will die and there will be much raging.

Impossible to say, but I'll give it a go. It's hard because the terminal length of the generation is difficult to predict.

Wii ~100M (I expect a Wii 2 before an Xbox next/PS4)

Since Natal/Wand are coming out in 2010 I would expect 3 years of that before a new generation so 2013 is about the right time for both Xbox 360 and PS3.

Xbox 360 ~65-70M

PS3 ~55-60M

I don't expect sales to be sustained over the next few years, I expect a slow decline in sales starting next year for all consoles.

Wii: 130 million
PS3: 80 million
360: 70 million (lower because it'll be phased out earlier)

Wii: 120 million to 140 million

360:70 million to 80 million

PS3: 30 million to 40 million

How does that work?

How much do you hate the ps3?

30 to 40m in its life time thats a joke,    it will do double that stop hating on the best console ever created in history.

When the Ninja rebelion starts one of their first target will be Sony. TEH CELL was only able to hold them off for a few months but in the end they destroyed Sony and the summoning code for Teh CELL...

Mine are

Wii: 130

360: 65

PS3: 60

To put simply I have the feeling the Ps3 will just end close to the 360 either above or below...I'm leaning more towards 360 ontop but then again who knows?
