Sony is killing it! Out shipping the Switch the last 2 quarters.

Seems a very arbitrary way of counting.

Vita 16.13M is 74.47M away from the average

Virtua Boy 0.77M is 61.53M away from the average

We could conclude though is that even when Sony fails it doesn't fail as hard as Nintendo. With PSVita that is deemed a big failure outselling WiiU and Virtua Boy, and being closer to the sales of N64, GC, WiiU than to any other system Sony released.

About doing one with only consoles I done it.

Using numerical difference instead of proportional difference is illogical.

By that logic a console that sold 95m compared to an average of 100m would be a bigger anomaly than a console selling 0.1m compared to an average of 5m.

Whereas selling just 0.1m compared to your usual 5m is clearly an anomaly, while selling 95m compared to your average of 100m is basically normal.

Ehhh.. that would depend on how much was the increase in units sold.

1000 units at $250 = $250,000 in revenue
850 units at $300 = $255,000 in revenue

Or how else would you explain that increase in revenue?

Absolutely desreved, Congratz to Sony.

I believe a smug Noire is very appropriate for this announcement

Okay guys, here is the question.

What will the lifetime sales look like?, Will it reach 120 million?, or at least 119 in order to beat the Gameboy? or will it end up arround 115 million?

At this point it should reach at least 120m.

It could go quite a bit further if they did substantial pricecuts post-ps5, as the amount of units sold after a successor seems very heavily tied to this.

PS1 shipped around 29m units after the PS2 launched, it had a price cut to $49 in May 2002
PS2 shipped around 48m units after the PS3 launched, it had a price cut to $99 in April 2009
PS3 shipped around 7m units after the PS4 launched, it's last price cut was to $269 with the launch of the superslim in September 2012.

So legs after a successor launch is heavily dependant on whether or not the console gets a substantial price cut after it's sucessor has launched. PS3 didn't and dropped like a rock.

I'm not sure we will see substantial price drops for the PS4 after the PS5 comes out, so my personal prediction will probably be around 125m. But if we saw a drop to $199 it could be as high as 135m-140m imo.

If there has been anything remotely close to a consensus here is that most of us expect 130M sold in the end for PS4. Nobody seems to disagree on that...

So boringly predictable is Playstation 4???

The bolded is great information to have, this is the "math" i had done on my own:

The PS4 had 91 million units sold at the start of this year, with a forecast of 15 million consoles to be sold this year which meant that next year the PS4 would be at 106 million, now obviously 2020 being the PS4s 7th year as well as the year the PS5 comes out means that the sales will have a rather big drop, however i believe the heavy hitters (TLOU2, Cyberpunk, FF7Remake) along with Ghost of Tsushima would help alleviate that drop in console sales, however lets be pessimistic and say that it goes from 15 million the year before to only selling 8 million next year, that puts the PS4 at 114 million which means it would need another 6 million (after the PS5 comes out) in order to reach the 120 million milestone.

i was unsure if it could reach those extra 6 million after the PS5 came out, but with the info (bolded) that you just provided me along with the info that Sony will keep supporting the PS4 for 3 more years,  i now have no doubts it will get there.

Still its odd thats its actually up by 2%.... I suspect most would be expecting it to have dropped YoY compaired to last.
However your explaination could explain it, maybe they didnt use as much/aggressive promotions this year as last.

BC + digital catalog = increased retention.

Stuff like this could have a small impact.

I suspect it ends up being 130m+, ofc this depends partly on how they handle priceing this year, next.
