Nintendo has revealed that the Wii U has sold roughly 400,000 hardware units during its first week of availability. The original Wii saw 300,000 systems sold and the DS outsold the 3DS 275,000 to 250,000; the 3DS has seen 6 million units sold in its first 21 months on sale.

“Wii U is essentially sold out of retail and we are doing our best to continually replenish stock,” said Nintendo of America president Reggie Fils-Aime. “Retailers are also doing their best to get the product to store shelves. But as soon as product hits retail, they’re selling out immediately.”

Despite Fils-Aime’s assertions, the Wii U is still available at a smattering of retail locations around the U.S. and can still be readily purchased online.
