Don't really have a leak but Zhuge said tthe 1.1m was fake.
Then, it was confirmed that PS4 was up YOY by 40% in November 2017, and we have 1.69m as leaked numbers. That's where i find my 1.2m estimate for Nov 2016
2020 predictions: NSW 21m, PS5 6m, XSX 4.5m, PS4 9m, XB1 3m
(PS5 and XSX predictions will most likely change after we know enough about them)
