It seems gamers in the land or the rising sun are taking their physical well being rather seriously these days. Nintendo’s latest cash cow of a product, Wii Fit, has been selling like hotcakes for the past four weeks. Wii Fit has sold close to 1.3 million (1,283,000) units since its December 1 launch last year, without relinquishing its number one spot in the sales charts for a moment.

But something tells me once the release dates for other regions are announced and Wii Fit released, Nintendo won’t be enjoying similar success outside Japan.
