In Mid-April we reported that the Wii Fit fitness accessory and game for the Nintendo Wii will be in short supply. Wii Fit has not even started shipping yet, but as far as I can see all major online retailers have stopped taking pre-orders.

Wal-mart, Amazon, Gamestop are just some examples of stores that mark the Wii Fit as out of stock.

Wii Fit will launch on May 21st. Most likely your next chance to get a Wii Fit will be in a mall near you on launch day.

Nintendo is supposed to increase the Wii console availability with the Wii Fit launch. I am curious to see if the Wii will appear on Amazon and other retailers for the normal price of $249 then.
