Somehow I am starting to doubt seriously that the Wii will ever pass the PS2...
I just can't believe that 6 years from now it still would be selling 120k/month like the PS2 just did...
If you believe NPD numbers the Wii is now tracking same as the PS2 was at a similar time after its launch too, roughly 80k/week.
The Wii is still ahead because it had outperformed the PS2 up to now but that period is now over...
