Nintendo has been proclaiming that the Switch is its fastest-selling console ever since the system launched, but now it has numbers to back that up. Based on NPD reports, it says the Switch sold 906,000 units in the US in March. What's surprising, however, is that The Legend of Zelda: Breath of the Wild is not just its fastest-selling launch title of all time, its Switch version actually outsold the console, moving 925,000 copies (add 460,000 for the Wii U and you have 1.3 million total).
