US games retail giant GameStop has stopped taking pre-orders on Nintendo's Wii U console due to 'overwhelming demand'. The firm announced today that it has instead "created a Wii U wait list exclusively for members of its PowerUp Rewards loyalty program".GameStop president Tony Bartel blamed the rushing Nintendo fans. "Demand for Wii U has been off the charts, he said, "and we know many of our PowerUp Rewards members are anxious to get their hands on one." "We're happy to offer our customers this exclusive opportunity to join the wait list for this must-have item," added Bartel. Customers are able put their names on the list via any GameStop store across The States, with no deposit required. Registrants will receive a notification when a Wii U is available for purchase and will have 48 hours to respond, but a launch day Wii U, at this point, would seem most unlikely. GameStop isn't the only US retailer to halt Wii U pre-orders - Target stopped taking orders on its website earlier this week. It seems Nintendo of America president Reggie Fils-Aime wasn't kidding when he told press that early Wii U pre-orders were "extremely strong".
