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?

And of course I put it in the Nintendo disscussion lol
Can somebody fix that?

Kinda off topic but I don't see the ps4 making it to 2020. I feel like it's going to continue to sell super well and more likely than not pass the ps3's sales but I think a ps5 in 2019 or 2020 will kill the ps4 especially if it launches at $400 and is backwards compatible

It's not off topic, if that's what you believe then so be it.

Interesting thread. Now, let's see:

2017: 17.5m
2018: 15m
2019: 12m
2020: 10m
Afterwards: 9.5m

Total: 114m LT

january 2018: 71 million
january 2019: 86 million
january 2020: 99 million
january 2021: 108 million
january 2022: 112 million
january 2023: 115 million
january 2024:117 million

Total sales: 118 million.

I don't think ps4 will reach 100million units I think ps5 will come out in 2018 and clause sale for the ps4 to decline

Ah yes, I love it, more posts like this please. Then someone bookmark this thread for when it passes 120 million :)

You're a hero!

2017 = 20 million - 73.4m

2018 = 18 million - 91.4m (New revision. PS4Pro Slim or Ultra or whatever + Price cut)

2019 = 16 million - 105.4m

2020 = 11 million - 116.4m (PS5 announced/released. PS4 starts to drop off big time)

2021 = 10 million - 126.4m (last price cut?)

2022 = 5 million - 134.4m

2023 and beyond = 4 million - 138.4m. So let's round to 140m lifetime.

I don't feel like doing math for totals, but that's what I can see. The PS5 could maybe release in 2021, but I think the PS4 specs will be too outdated at 2020 so I dont know. Those also look like very big numbers, but the PS4 likes to do that.

Do we have any idea how the PS3 sold after the PS4 released?

Edit: I tried doing math.
