Many people have been asking what Nintendo can do to improve on the Wii console that has taken the world by storm.
Since the Wii's release in 2007, more than five hundred million consoles have been sold, making it more popular than cabbage. The WiiFit, the balance board that can be bought separately has been bought by most Wii owners, making it more popular than breathing.
The combined sales of Wii extras on top of the console itself has turned Nintendo into the world's wealthiest company, giving them so much money they sponsored Barack Obama's presidential campaign by having him repeat the slogan "Yes! Wii Can!"
With popular titles such as WiiPlay, WiiWee, WiiAct and WiiKling, it is estimated that at any one time, a quarter of a billion people are playing on a Wii.
Questions have now been asked as to how Nintendo can follow up on the Wii to produce something that will make a twelfth of the world's population give up their favourite toy and switch to something new.
Leaked memos from the Japanese headquarters are giving some clues.
"Having introduced the concept of exercise to gamers," said Matt Shaker, of the Wii Gamers Website. "It looks like Nintendo are ditching the physical box, and having people take up jogging, tennis and golf for real. It should retail at about £200, with add-ons, like training shoes, sold separately."
