success of the Wii has Nintendo feeling pretty confident about themselves. They've sold about 2.5 million units since launch, and probably would have sold more if there had been more.
Naturally, the six months following launch are completely representative of the console's whole life cycle, which is why Nintendo of America VP George Harrison, in a statement to Bloomberg, was confident enough to predict that the United States would have an install base of 35 million Wiis by 2012.
We aren't business experts, but we think Harrison might be committing a Disco Stu Fallacy here. "Did you know that disco record sales were up 400% for the year ending 1976? If these trends continue...ayyyyy!"
