Staring June 18th, as per Gamestop, all locations were instructed to start sending back all unsold Wii U Basic inventory.

According to Kotaku Gamestop issued this notice to retailers: Nintendo Wii U Basic Recall - Two Week Preparation On Tuesday, 6/18, all stories will need to return all new/unopened Wii U Basic (020359). .. Stores that have 10 or more in stock will receive shipping cartons from the [distribution center]. .. All other stores will need to save shipping cartons for this recall.

There seems to be some miscommunication between all involved as Nintendo of America director of corporate communications Charlie Scibetta, clarifies, “There is a current misconception about Wii U hardware. To clarify: Nintendo is working with its retail partners to simply rebalance the stock of the White 8GB and the Black 32GB Wii U models in the market. Consumers looking for either model will continue to find them available.”

After reading the Nintendo statement, it appears that they have not actually addressed the rumor specifically, they only say that they are re-balancing stock and it will continue to be available for sale, even though the notice clearly states recall.
