Despite some Joy-Con issues and Nintendo’s insistence that dead/stuck pixels aren’t a defect, the Nintendo Switch is selling like hotcakes. SuperData reported last week that the device sold around 1.5 million units in its first week. Now, a GameStop exec says it has the potential to outsell the Wii.

Speaking to GameRant, GameStop’s senior director of merchandising, Eric Bright, called the Switch a “transformational piece of technology” that could go on to perform better than Nintendo’s 2006 Wii, which, with more than 100 million+ units sold, is the fifth best-selling console of all time.

The Nintendo Switch is off to a start right now that it could possibly eclipse the Wii. Initial sales on this have been phenomenal. I can’t give straight numbers, but I can say we’re seeing one of the highest attach rates of software and accessories to a device that we’ve seen in a long time

Nintendo itself has yet to release any sales figures for the Switch but may do so in its next earnings report on April 27.

If the Switch does eventually pass the Wii on the best-selling consoles list, don’t expect it to happen anytime soon. It took four years after release for the Wii to reach 67 million sales, and it didn’t hit 101 million units until 2012 – six years after launch.

Nintendo had originally anticipated that the Switch would sell 40 million units over the next four years, but it may be rethinking those predictions given how many retailers can’t keep up with demand. The handheld hybrid is certainly on course to quickly outperform the Wii U, which only sold around 14 million units.
