wii - 40
ps3 - 40
xbox360 - 35
Ok I'm absolutely certain that these numbers are totally off. Wii will either fail miserably in the next couple of years or continue selling like that and hit somewhere around 100 mil. It really depends on whether casual and non-gamers will continue buying it.
Ps3 is so grossly underestimated that I can't even believe those guys :/ GT3 is the best selling ps2 game and it came early in the beginning of ps2 life. I think it sold around 16 mil worlwide. Obviously it's a HUGE system seller. By the time gt5 comes out the ps3 will be probably around 400-450$ which is pretty reasonable. Also we have other big system sellers like mgs4, and ff13. Even gta4 although it's on 360 as well will probably sell quite a few consoles. Not to mention all the smaller IPs and new ones :/ I mean seriosly there are just way too many system sellers for it to sell anything less than 40 mil and that's the bare minimum.
The 360's future is also very unclear. It has much better game support than the xbox but with the RROD problem it'll make most gamers think twice whether they want to buy a 400$ console that they'll have to replace in a year or two :/ If MS manages to fix this problem I would think they'll get to around 60 mil maybe even 70.
