Nintendo plans to sell 35 million Wii consoles in the United States by 2011 or 2012.

Nintendo wants to get close to the success of Sony's PS2, which sold 38.2 million consoles in the U.S.

Clearly Nintendo tanked lots of self-esteem with the runaway success of the Wii console world-wide. Sony has a slower start with the PS3.
Nintendo sold 2.5 million Wii so far in the U.S. Sony stands at 1.3 million PS3 consoles sold.

In 4-5 years I hope that we actually see a new Wii console that is HD and makes good on the hardware performance side of things.
