Nintendo sold over 906,000 Switch units in the United States alone last month, making it, as they bragged in a press release tonight, the fastest-selling video game system in the company's long history. Combine that with half a million in Japan and you've already got nearly 1.5 million of these things, not counting Europe (where we don't have up-to-date numbers).
For comparison, the Wii U sold 890,000 units in the United States during its first six weeks on the market. That was during the holiday season, of course — the Wii U came out in November of 2012 — which makes the Switch's numbers look even more impressive.
Nintendo added that they have sold 1.3 million copies of Zelda: Breath of the Wild in the U.S. — 925,000 on Nintendo Switch and 460,000 on Wii U — and you may notice that they have sold more copies of the Switch game than Switches themselves for an attach rate of over 100%, which is certainly one hell of a number.
"While Nintendo Switch sales are off to a record-breaking start, shipments have not yet been able to keep up with such high demand," the company said in a press release. "Nintendo is working to make sure everyone who wants a system is able to buy one, and more systems are continually being shipped."
Based on the Switch's success, we can only assume that Nintendo will soon discontinue it.
