I would really like to know where they get this stat. I guess it's a reference to March 2008 NPD sales versus March 2009 NPS? Still, the quote makes it sound like Wii sales are down for the entire year, when in fact Wii had not only its best Q1 in the US yet, it had the best Q1 of any video game system in the history of the American market, ever. I think the Gamasutra chart is approprite to mention here:
End of 2008 totals: Wii 42m, 360 24m, PS3 18.5m (made Jan. 4, 2008)
