UPDATE – added Nintendo statement

As spotted by Videogaming247.com, online retailers including Game.co.uk, Play.com, Amazon.co.uk and Zavvi.co.uk have stopped taking pre-orders for the game due to “massive demand”.

Wedbush Morgan analyst Michael Pachter said Tuesday he believed Wii Fit could drive “a new boom in demand for the Wii”. He previously noted that a record-breaking $40 million marketing budget could help Nintendo sell four million copies of Wii Fit in the US alone during 2008.

Wii fit is set to launch in Europe on April 25 and in the US on May 19.

Next-Gen has contacted Nintendo and retailers for comment regarding Wii Fit supply.

In a statement released to Next-Gen, Nintendo said it is endeavoring to ensure that consumers can get their hands on a copy of Wii Fit come launch day.

“All retailers in the UK and Ireland have been aware of their Wii Fit allocations for launch since early March and as such we would see any stopping of pre-orders a sensible precaution on their part to ensure all current orders are met. Many retailers are still accepting pre-orders and we would advise people to shop around to secure their copy.

“As with all our launches, we are working very hard with all our retail partners to be as open and as transparent as possible with further deliveries. We’re disappointed if even one person can’t get hold of one of our products and we are doing everything we can to ensure we have as much stock as possible coming into the UK and Ireland not just at launch, but continually, to try and minimise any potential disappointment as much as possible.”
