Nintendo Wii Fit going to increase Wii sales

The Nintendo Wii has been the leader in the field of video game consoles, leaving the much more powerful Sony PlayStation 3 and the Microsoft Xbox 360 way behind. Consumers have been attracted by the power of the simplicity of the console and its usability, specially the motion sensing capability of the Wii remote that allows users to be more interactive with the game and brings a much better handling of the games. This has continued, with the Wii steadily out-selling the other gaming consoles, and more games being written for the Wii over a period of time (inspite of the much more powerful marketing power of Sony and Microsoft).
Now, Nintendo is coming out with a game that is very eagerly awaited, and promises to let people overcome the couch potato effect of a video game console, instead they get a way to become fit:

Nintendo will be releasing the newest of its exercise games, the Wii Fit on May 19th and you can expect it to fly off of the retailer shelves. But just who will be buying it? Many expect that our mom's will be buying them, at least according to some analysts and some research. The Nintendo Wii has been more popular among women than the Microsoft Xbox 360 and the Sony PlayStation 3, but some analysts believe that this game that combines exercise and entertainment will help put Wii sales over the top again.
Wii Fit will retail for $89.99 and will include a balance board to facilitate the more than 40 yoga, aerobics, and strength training exercises. The user sets their own fitness goals and keeps track of their progress over time.

If this truly turns out to be well designed, then this well and truly ensure that Nintendo keeps its lead over the other game consoles; further, there are not many analysts now who actually believe that Sony and Microsoft will be able to challenge this dominance in the near future.
