Nintendo Switch sales have surpassed those of the Nintendo 3DS and are on track to outsell the Wii by the end of this year.

Nintendo just released its latest financial earnings release for Q3 of FY21, and the numbers are impressive, to say the least. As of December 31st, the Nintendo Switch has sold 79.87 units globally since its launch back in March of 2017, thereby beating global lifetime sales of the Nintendo 3DS (75.94-lifetime sales). This means that over the last 9 months (from Q1 to Q3) Nintendo managed to sell another 24.10 units Switch units, including 16.77 ‘regular’ Switch units and 7.33 Nintendo Switch Lite units.
