I feel like PS4 is peaking 2017. So:

PS4: 17M
NS: 20M (barely managing it over the holidays)
X1: 7M
3DS: 5M



3DS-FC: 4511-1768-7903 (Mii-Name: Mnementh), Nintendo-Network-ID: Mnementh, Switch: SW-7706-3819-9381 (Mnementh)

my greatest games: 2017, 2018, 2019

Predictions: Switch / Switch vs. XB1 in the US / Three Houses first quarter
