Whoever is putting 200+ million for the Wii keep in mind the DS is selling way better and yet it has to sell more then triple what it already has to to reach 200 million. As the ps3 has better games and the 360 continues to come out with strong brands it will be hard for the Wii to continue at it's pace long enough to make those kind of numbers. hardcore gamers may become more interested in the other systems more dedicated to hardcore games, and casuals don't tend to stay hot with one gadget for too long. I'm not saying it one win with flying colors, but 200 million is a bit steep at this point.
For those saying the X360 will only get 35 million. That is a bit low, this system will stick around for a while and has lots to offer the gaming publics it's already more then half way to 35 million and we're not even halfway through this generation, wait till it becomes more reliable, and cheaper, there is no reason this system won't fly right pass 40 million and park it's lifetime userbase between 50-60 mill.
