ASDA will no longer stock Wii U or any games for the system

Massive UK retailer ASDA which is owned by the US's Walmart chain will stop stocking the Wii U and all related games and accessories in all of its 555 stores. An Asda representative confirmed the move with CVG:

Asda continues to offer customers a selection of Wii U games and accessories through Asda Direct, but these ranges are currently not on offer in Asda shops.

The move is clearly due to lack of Wii U sales that have hounded the system since launch, and this could be another big blow. Even launch games such as Zombie U by Ubisoft failed to make a profit despite being praised for uniqueness.

Nintendo also issued a statement to CVG:

Nintendo UK does not comment on specific business practices with individual retailers. However, as we have seen with Nintendo 3DS, software sells hardware, and with titles such as Wonderful 101, Legend of Zelda: The Wind Waker HD and Super Mario 3D World already announced for this year as well as the recently released Pikmin 3 and New Super Luigi U having reached number 2 and number 6 in this week's chart respectively, we are looking forward to the year ahead on Wii U.
