Nintendo's Wii has emerged an unlikely winner in the three-pronged games console race between Microsoft's Xbox 360, Sony's PlayStation 3 and itself.
To date Nintendo has sold at least 2.5 million consoles in North America.
Wii's popularity has soared to such an extent that games publishes are making exclusive Wii-oriented games. Prime among these publishers are Electronic Arts, Ubisoft and Disney.
