This makes the Nintendo Switch the company's fastest-selling video game system of all time.
As a response to this stronger than expected start, SuperData now projects that the Switch will sell 7.2 million consoles in 2017.
Meanwhile, the console's biggest launch title - The Legend of Zelda: Breath of the Wild - sold over 925,000 units for Nintendo Switch, somehow outselling the console itself, and almost 460,000 units for the older Wii U console.
And now, analysts have predicted Nintendo will be trying to capitalise on the popularity of its latest console with another Switch device in the future. On the other hand, The Legend of Zelda: Breath of the Wild - Switch's launch title - had been managed to have 925,000 copies sold in March.
Nintendo has finally revealed some concrete sales figures for its new hybrid console/handheld, the Nintendo Switch. So it's not that hard to believe Nintendo's boast that it was able to sell more than 906,000 Nintendo Switches in March, as least in the United States only. And the Nintendo Switch therefore has broken all records.
Of course, stocks are still low deep into April, with Nintendo saying that they are "working to make sure everyone who wants a system is able to buy one, and more systems are continually being shipped". More than a few gamers have purchased Zelda: Breath of the Wild on Switch simply because they can't find a Switch console in stores.
In second place, the PlayStation 4 outsold the Xbox One in March, making it the fifth month in a row.
Now research firm SuperData is coming out with its own predictions regarding Switch, and if their calculations are correct then Nintendo is in for quite the year. The rendering of the game on the Nintendo Switch is astounding, with sharp and bright screens with powerful stereo speakers.
