Nintendo has sold 14.86 million units of the Nintendo Switch in its current fiscal year, according to the company’s own numbers, with 52.57 million units of software sold alongside the system through Dec. 31, 2017.

That’s an amazing accomplishment for a console that’s less than a year old, and it already beats the Wii U’s lifetime sales of 13.56 million units of hardware. The Switch launched worldwide in early March 2017.
