Earnings reports began appearing for a number of video game companies on Tuesday, and with those came Nintendo's unsurprising confirmation that its Switch hardware is doing quite well. Now we know exactly how well: it needed less than 10 months to surpass its predecessor, the Wii U, in worldwide sales.

Nintendo's latest earning report includes a breakdown of lifetime hardware sales for the Nintendo Switch, Wii U, and Nintendo 3DS family of consoles. Its "as of December 31, 2017" figure places the Nintendo Switch at a current lifetime sales count of 14.86 million units, surpassing the 13.56 million Wii U units sold in a little over five years. The Nintendo 3DS (and its 2DS and "New" variants) have combined to sell 71.99 million pieces of hardware since launching nearly seven years ago.

Originally, Nintendo had told its shareholders to expect first-year Switch sales of 10 million; the company revised that estimate in October, following its last earnings report, to a first-year tally of 14 million worldwide. That has now been exceeded a little earlier than expected. The traditionally slow game-hardware months of January and February will likely pad the Switch's first true 12 months of sales data, if only a bit, due to a lack of major or exclusive Nintendo software during that span of time. Nintendo fans will have to wait until March for a new Kirby game and April for the weird, build-your-own-cardboard experiment of Nintendo Labo.

While waiting for more games, more than 9 million Switch owners worldwide may still be busying themselves with Super Mario Odyssey, according to Nintendo's 2017 game sales figures. That puts Odyssey's Switch attach rate at a crazy-high ratio in spite of not being a launch title. Other major first-party game tallies include 7.33 million copies of Mario Kart 8 Deluxe, 6.7 million copies of Legend of Zelda: Breath of the Wild (though it's unclear if that figure includes copies of that game for Wii U), and 4.91 million copies of Splatoon 2. The company's newest (and darned good) franchise, Arms, was actually outsold by the lukewarm launch party game 1-2 Switch.

The Wii U's rough lifetime sales are perhaps best understood in the context of that list of software above. Major open-world Mario and Zelda games, along with a wave of solid download-only games and third-party games that people actually wanted to play, actually arrived for the Switch's first year, compared to the Wii U's mix of big-game waits and failed pushes of second-screen gameplay concepts.

Those sales figures put the Switch on track to surpass the GameCube's lifetime sales figure of 21.74 million and perhaps even the Nintendo 64's lifetime tally of 32.93. Still, Sony rules the modern roost with its own blistering PlayStation 4 sales, which exceeded 73 million units sold worldwide by the end of last year—and which Sony believes sold close to 18 million units in 2017 alone.

In other sectors: Nintendo's end-of-year disclosures didn't confirm specific sales figures about the Super Nintendo Classic Edition , beyond stating that the system "proved to be a hit." Meanwhile, the company's "smart devices and IP-related income" was through the roof, at 29.1 billion yen (or roughly $265 million), though it's unclear how that figure is divided amongst various games, including the Niantic-developed Pokemon Go , and any other "IP-related" efforts such as licensing.
