I've posted on other chart threads that after 80m is a bit more difficult to find buyers because there's some level of saturation, however it's not even close to total lack of potential customers. Not only many families do buy two home consoles of the same brand but many gamers buy the same brand more than once in one generation for many reasons. Besides, there are more than 80m people out there ready to pick up a PS4, specially with a price cut.

80 + 37 + 14 + 17 = 148

But it is ok I see your point.

This wants me to make some calculations...

Of those 7B inhabitants, around 1B have both access and financial possibility to buy a console. Dividing it into households (since most households will only buy one version of a console per Generation - though the upgraded versions skews that number around) and we get a total maximum of around 250-300M customers, twice that number if everybody bought a base console and then upgraded to Pro/X.

Since many households will only buy one console total, we could settle the total potential market for consoles per gen at around 300M

Handhelds cater more to persons than to households. As a result their theoretical potential market is bigger, but in practice outside of kids most customers are persons who are moving a lot without being the one to drive (mass transportation like buses and trains, but also taxi/Grab/Uber/Lyft and persons who fly often), which tends to make their total market smaller than the console market, especially in more rural regions. Add to this that smartphones are eating on their share and you can see why outside of Nintendo nobody seems to take that gamble anymore.

Total potential market for handhelds is hard to gauge, but I guess around 100-150M

Switch, being a hybrid console, fuses both markets together into one. But PS4 and XBO already have a big chunk of those 300M potential customers and still selling great, so over a third of those sales are already made. However, Switch is basically the successor of the 3DS (and in a way of the Vita, since it's conceptually closer to that and Sony didn't announce a successor yet), giving it additionally most of the handheld market. This would give the Switch a potential of 200-250M customers.

Of course, it's impossible to cater to everybody, so those numbers are pretty much impossible to reach. However, with such a great potential, it's not impossible to sell something close to PS2 or DS numbers, though not necessary probable. Time will tell how well it will do. The PS4, if it doesn't drop too fast, can get close to that number, too, but probably will fall short by 20-30M. Xbox ONE is the weakest of the three, even though it has recovered a bit with the ONE X, it's not selling well enough on a worldwide stage, catering mostly to it's home market. 60M may be doable, but that will be the maximum reachable for the console.

huum, yeah... with this trend, looks like PS4 is gonna be overtracked by a good million, considering that it hasn't surpassed 80million in June, and with the VGC basis it should surpass 81 million in less than 4 weeks.

Btw, am i the only one surprised Sony hasn't annunced that milestone yet? PS4 should be seriusly super close to 80 million.

Same here, though it's possible they passed it already, just not in time for E3 where they possibly wanted to announce it.

also for once since forever ago, its slowed in selling 10m more units, than the last 10m before it.

From 60m->70m only took 175 days,...... its apparent that from 70m->80m is probably like 190days+.
So its slowed abit in sales.

However I still think they where hopeing they could announce 80m at E3 like you do.

Sony should release cheap top loading PS4 this holiday for 249

They've announced other milestones at random times before. It's probably just about to pass 80 million any day now. But maybe they want to wait for 85 or something

199$

A cheap Super Slim PS4, would be awesome.
