This is significant not so much just because sales keep climbing - I could have told you that would eventually happen - but because of the differences between the Switch and the GameCube that highlight how Nintendo has changed and adapted to the changing market.
For context, this puts the Switch past the GameCube, Nintendo's sixth-generation console which debuted in Japan in September 2001 and went on to accumulate 21.74 million in lifetime sales.
"Nintendo Switch hardware continued to be quite popular, reaching 5.07 million units sold" in the April-September period, it said.
Nintendo's Switch now has more lifetime sales than the GameCube
The company previously stated it expects to sell 20 million Nintendo Switch units in the fiscal year ending on March 31, 2019. You can look at these figures yourself over on Nintendo's official financial report page. The company has also sold 111.10 million software units for the Switch.
Nintendo's quarterly sales growth slowed to 1% year-over-year, which is the worst pace for the company since the Switch launched. Donkey Kong Country: Tropical Freeze, a game that originally released on Wii U, has sold 1.67 million units. This includes first, and third-party games. A flurry of highly anticipated games launching in the coming weeks will be crucial to Nintendo being able to hit its goal of selling another 20 million consoles over the next six months.
Overall, Super Mario Odyssey remains the Switch's top-seller, with 12.17 million, followed by Mario Kart 8 Deluxe's 11.71 million, and Zelda: Breath of the Wild with 10.28 million.
