You guys made the Wii the biggest thing since sliced bread. Before 2008, no video game console had ever been purchased by 10 million Americans in a single year.
The NPD Group says that Nintendo sold overall 10.17 million Wii consoles in 2008 in the United States alone.

Even the Nintendo DS sold close to 10 million units with 9.95 million in 2008. The Wii captured 55% of all next generation home console sales (PS3, Xbox 360) in 2008, while Nintendo DS claimed 72% of all portable system sales in 2008.
The Nintendo impressive 2008 records also include the top 4 spots in the bestselling game charts with Wii Play at No. 1, Mario Kart Wii at No. 2, Wii Fit at No.3, and Super Smash Brothers Brawl, at No. 4.

Despite the economic downturn the overall video game industry revenue grew by 19% compared to 2007.
2009 might even be a tough year for Nintendo unless they bring something new. I cannot imagine Nintendo reaching again 10 million in Wii sales this year without a new impulse. Of course a lower price could also just do the trick. An in-stock $199 Wii could activate yet another couple million buyers.
