As we know from January 1st 2017 to June 11th 2017 the PS4 has sold 7 million units (53.4m to 60.4m). That's 5 months and 11 days, it's fantastic stuff.
So It's got me thinking how it would be fun to predict when it would reach certain milestones, or what it would sell by the beginning of each year going forward. So I'll start (bear with me, first thread lol):
Sold by January 2018 = 72 million (18.6 million in 2017)
Sold by January 2019 = 88 million (16 million in 2018)
Sold by January 2020 = 103 million (15 million in 2019)
Sold by January 2021 = 113 million (10 million in 2020) (Year PS5 launches)
Sold by Jaunary 2022 = 119 million (6 million in 2021)
Sold by January 2023 = 122 million (3 million in 2022)
Sold by January 2024 = 123.7 million (1.7 million 2023) (10 years on the market)
Lifetime Sales = 125 million
Honestly I think I'm being conservative for a console that will probably sell at $149 when the PS5 releases in 2020 with frequent sales at $99.
What say the forum? Am I lowballing it or is it ludicrously optimistic?
