The Witcher 3 sold about as well last year as it did at launch

The Witcher 3: Wild Hunt has had a really good year.
The Witcher and Cyberpunk developer and publisher CD Projekt has announced the financial results [PDF] for 2019.
The Witcher 3: Wild Hunt was a major contributor to the company's revenue in 2019. During that year, sales of the game across all platforms came close to The Witcher 3's all-time high at its launch back in 2015.
Though specific figures weren't mentioned, the document reveals that sales in 2019 were around 7 million, compared to 9.5 million in 2015. This is the highest tally by far since launch.

PC was the dominant platform in 2019, just like it was for 2018, 2017, and 2016. 53% of copies were sold on PC in 2019, compared to 26% on PS4 and 10% on Xbox One. The launch of the Switch version in October amounted to 11%.
82% of all sales made in 2019 were digital, compared to just 29% at the game's launch in 2015.
These figures aren't surprising, considering the boost the Netflix show gave the game, particularly on PC, where it helped it set all-time high player records on Steam. The Switch launch also played a part, despite how late in the year it was.
2020 similarly promises to be big for CD Projekt, with the launch of Cyberpunk 2027 in September.
