wii the wii be the third game system to reach 100 million or the ps3?

[Grey Acumen]

Guys, I think it's impossible for the Wii to not make it to 100 Million.

It's selling twice as fast as the PS2 had
is the cheapest of the 3 current gen consoles
is being sold at a profit
hasn't had a single price drop yet, but obvious can at any time it's deemed necessary
is marketing to a wide audience from the very beginning
still has yet to introduce new colors
hasn't introduced any new design (DVD support, hard drive, not likely, but possible)
has only just started to implement features that incorporate the DS

and Nintendo has stated they'll support the console for as long as there is call for it so that means that its lifetime will easily be as long as the PS2's.
This is not a fad, it will not stay limited to just casual games. The DS started with Nintendogs as its big IP, but now it has plenty of different games of varying intensity.
The Wii is well on it's way to 17 million, possibly 18 million, and that is only because of Nintendo's limited production rate. Even the most conservative predictions should be based on Nintendo selling just as much each year, which would put it at roughly 15 million every year.
15 x 7 + 3(from 2006 sales) = 108
Keep in mind, the actual sales will likely be higher, so even if Nintendo does decide for some reason to come out with a new console in only 5 years, the Wii would likely be approaching the 100 million mark by this time and will still creep into the 100 million mark by its 6th to 7th year.
