According to Nintendo data, this is their track record of worldwide sales over the last four generations of consoles, and it isn't good. Obviously the GameCube hasn't done as well as Nintendo hoped, and handhelds make up a huge amount of Nintendo's marketshare, but who knew that their home console sales had declined so drastically?
Of course, maybe it doesn't matter how many units Nintendo sells if at the end of the day, their numbers are in the black. And I have a feeling the Wii will fare a little better. Predictions anyone? Hard numbers only!
