News about the insufficient stocks of Nintendo’s Wii console begin to surface again. The game was launched about 18 months ago and every once in a while a general frustration appears amongst the game’s enthusiasts as the stocks are not refilled on time.

Some say that the company’s rather slow production strategy is influenced by the sales failure of their last console, the GameCube.

At the moment, the massive consumer demand for the Wii and the Wii Fit in the United States cannot be covered by the company’s production plan and it will surely go down as a big missed opportunity, as IDC analyst Billy Pidgeon put it.

Other analysts believe that the huge overseas shipments led to the current situation and that Nintendo prefers the euro market to the declining dollar’s, as it turned out to be much more profitable for the company. Wedbush Morgan Securities analyst Michael Pachter explained for the Los Angeles Times that Nintendo’s strategy caused the shipping of over 2 million units in Europe, while only 500,000 were sold in the United States.

Apparently, the game is completely sold out in stores all across the US but a Nintendo spokesperson explained in a statement that the exceptional consumer response for the Wii Fit game took everyone by surprise and all efforts are now focused on replenishing the stocks as soon as possible.

A total estimate for the game’s global sales has not been presented so far but the sales estimates in Japan put the Wii at more than 2 million units sold since its launch.
