There are a lot of loud Nintendo and Xbox fans(last generation ps3vs 360) zooming around the internet who likes to beat down the sales of ps4 as if it somehow makes their console look better. The reality is ps4 is the king this generation. I think 2019 sales will be 17million; 2020 sales will be 12million. So back to your original question, that's 123million in sales. Probably another 10 million after 2020; so lifetime sales of 133million.
