A reliable retail source tells us that some GameStop chains will no longer be selling the 8GB Wii U as of June 18, exactly one week after Nintendo's big E3 kick-off event. Our source says GameStop has contacted stores with the following message: 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. What's this mean? GameStop officials have not replied to our request for an official comment; we'll let you know if they do. Nintendo tells us: "We do not comment on our business practices with retailers." That's not helpful! Product recall for a defect? Or some pre-E3 removal of inventory to get ready for a price drop for the 32 GB model? Or just a discontinuation of the 8GB model? We don't know, but our retail source has a good track record. We'd love to hear from more. The 8GB version of the Wii U costs $300 and is white. Nintendo sells a 32GB model for $350 with Nintendo Land packed in. The Wii U launched on November 18. It's a good system but has been plagued by a lack of compelling first-year games, something Nintendo hopes to change with the looming releases of Pikmin 3, The Wonderful 101 and promised new Zelda and Mario adventures.
