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

With Sony themselves saying that this past Black Friday was the best one in PlayStation history, I'm beginning to suspect that 2017 will finish around the 21-22 million range. Extremely impressive, indeed!
Perhaps even more impressive is the potential of 2018 with the strong 1st party lineup Sony has put together for that year thus far. Between God of War 4, Spider-Man, Detroit, and Monster Hunter, I believe we'll see another 20 million. And that's without the price cut.
