After just eight months, Nintendo's Wii, with its innovative motion-sensitive controller, is surging to the top of the next-generation video
game sales charts. It will soon surpass Microsoft's expensive Xbox 360, which had a one-year head start, in total sales. Moving forward, its only possible setback is a supply shortage as Nintendo
struggles (admittedly) to meet demand. Meanwhile, Nintendo its portable DS game system, on the market for nearly 3 years, has sold 47.27 million units worldwide, far outstripping Sony's PSP.
To be sure, Nintendo's next-gen rivals are struggling. According to research firm VGCartz.com, Sony has sold just 3.69 million PS3s to date. Microsoft has sold 10.15 million Xbox 360s, but it's set to lose that lead after selling just 420,000 consoles in Japan--the industry's biggest market--in 18 months.
