PS4 Hardware Sales 2015 vs 2016 vs 2017: New Years numbers posted. 2017 ends at 20.2 million

[Empire(of)Tears]

I think it wont have such a great Holidays Season in USA and Japan.
There is new xbox + switch in USA - i think those gonna be the hottest products of the December.
Japan is now moving to switch. The last bastion is Europe, impact of the new xbox and switch will be smaller here, but still recognisable.
For me 2017 is the last year when PS4 gonna sell more than 15 million system.
