Apparently, gamestop store managers received this note from the company:
Nintendo Wii U Basic Recall - Two Week Preparation On Tuesday, 6/18, all stores 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.
So, basic Wii U consoles are being recalled from gamestop, while 32Gb ones are not, at last at the moment. The reason is a mystery. Are they going to retool them and put them back on the market with a bigger storace device? Or is this the beginning of the Wii U going the way of the Dreamcast?
