With next generation starting in 2012 not a chance.

But lifetime PS3 will outsell Wii in Japan and EMEA and X360 will outsell it in America.

The odds of PS3 catching Wii in Japan are practically nonexistent unless Wii well and truly dies there before the end of the year, which is highly unlikely considering DQX has yet to come out. On the other hand there is a very real possibility that PS3 might take EMEAA in the long run if Sony follows the same strategy of aggresively moving into emerging markets like they're doing with the PS2. But that of course assumes that Nintendo doesn't, and we really have no idea what their long-term strategy is for the Wii. I'd say 360 has a shot at taking Americas but it really comes down to at what point saturation starts to cut into its sales.

DS wins everywhere

Wii to be 40M plus LT inEMEAA, 50M plus LT in America and 13M plus LT in Japan, Wii successor will come lat 2012, but maybe all the rumour are just bull and wii sucessor comes early 2013 if a price cut and new software can drive wii for another year or 2.

I think PS3 has more of a chance of winning EMEAA back.

It's not like the gen ends when the next system comes out, to me a gen dies when its last console dies.  You can have two gens going on simultaneously, even if one is completely non-competitive anymore (PS2 gen). 

Well, the easiest way to do this is first attempt what Wii will sell in each region. There is no way in hell Wii 2 launches in 2011 - Nintendo doesn't have the software resources, and there is no reason to have it compete against 3DS and Kinect as the hot new thing at least in the West.

In a best case scenario, the numbers for all three systems could be as high as what I show below.

For Wii 2 I'm assuming:

$300, 300 LBP, 300 Euros, 30,000 Yen. Spring (Apr) 2012 launch in Japan, November 2012 launch in the West.

For X720 / PS4:

PS3 launched in 2007, compared to 2006 for Wii, and 2005 for X360 in Europe, so the 2005-2010 data favors PS3 (16.8m in 46 months) over X360 (15.5m in 62 months) pretty substantially (110k in favor of PS3 / month on average) in Europe. Wii is in between for months (49), and thus sold 26.9m in 49 months. Math is 550k / month for Wii, 365k / month for PS3, and 250k / month for X360 on average rounded to the near 5k.

           Americas          JP             EMEAA      World Sellthrough      World Shipped

Wii        63.2m           15.5m       53.3m           131m                            135m

PS3       33.1m           10.6m        50.3m          94m                               98m

X360     53.0m           1.8m         36.2m          91m                               94m

Realistically, Wii can probably be anywhere from 115m - 140m yet (it will be trending below PS2 soon on a global basis - starting sometime in 2012 - but PS2 is going to be at 160m or more by the time its done), X360 anywhere from 65m - 95m, and PS3 anywhere from 70m - 100m (135m - 195m for the HD consoles as a whole essentially). PS3 has been trending 40% below the PS2 pace for about a year now, so the question is how high PS2 gets really and whether PS3 can stay at 40% behind. X360 was way off the PS2 pace but has been catching up a bit with the USA / UK reacting strongly to Kinect.

Personally, I think Kinect was enough of a lift to prevent PS3 from trouncing X360 long term but probably not enough to get X360 ahead lifetime, even though it will be ahead most of the race.

See how the 3DS has killed the DS? Yeah you all are too optimistic :P 

Have you seen Japan's figures lately? The PS3 is selling about twice as much as the Wii nowadays.

Nope. Wii will remain top in each region. Nothing at this point is going to change those gaps from 1st to 2nd in any region.
