If I remember correctly, the PS4 also sold better in 2018 than in 2017.
VGChartz numbers have PS4 at 19.75m for 2017 and 18.25m for 2018.
I do think there are a few other rare examples though, hence "almost" unprecedented.Last edited by curl-6 - on 20 January 2023
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023. (And over 130 million lifetime)
