I want a Ninstation, so I'll go with that.

The problem is you want to combine every gaming system of the market as one whereas I see the handheld division as a separate entity from home console, this mean that if you want to predict Nintendo next home consoles sales, you can't take into consideration the handheld sales because the curve for both of them are very different.  Nintendo handheld business has shown consistency, thus thinking the next nintendo handheld will sell over 80m is reasonable but you can't apply that to the next nintendo console because they have behave in a different way.  The same way I remembered people predicting that ps4 was  going to flop because Ps vita flopped, you know, being the most powerful and all that and look how that turns out.  Sony home consoles has shown consistency whereas sony handheld division has shown huge declining, thus can't use one of them to predict the other.  If you want to predict home consoles sales, have to look at prior home console sales, the same way it works for handheld.

for the bolded, that's why I use 80m and not 100m because every consoles has sold at least 80m, one console showed that 100m isn't the minimum and with ps4 sales dominating this gen, you can't conclude that ps home console are in declining because ps4 is way ahead of ps3 and it's the console leader right now.

It will sell exactly as many as the PS4 and will be called PSNow.

I'll go with ~7,000,000,000 . The PS5 will be so awesome, that if you don't own it, you officially do not form part of the human race.

But that's the reason... "every PS console sold more than 80m" maybe because the PS under 80m is not yet released!

The example what about every console before the PS3 sold more than 100m because the PS3 was not coming... then, we have the dropped of Sony minimum sales.

PS1 100m -------> PS3 80m

So, how you know the next gen can be for example 80m -----> 70m? 60m? 50m?

And for the firsts, we can't say that the PS console are not similar, because 100m to 150m is a 50% up, then 150m to 90m is a 40% dropped, then PS4 can be up to PS3 by 0% to 50%...

But that's the point, there was a declining to 80m from ps1 to ps3 thus thinking that ps4 might hit less than 80m was reasonable because there was an expected decline due to the new popularity of xbox but now that ps4 has been on the market for more than one year and a half showing that it's on pace to outsell ps3 and that it has managed to regain that marketshare lost from last gen , we can't no longer think that ps consoles are in decline and thus the minimum so far will be 80m.  Can the next home console sell less than 80m, of course it can but right now, there is no history indication that that will be the case.  If you want to believe that it will sell less than 80m, I will see it more as a wishful thinking than a analytical prediction.

For the last sentence, all I see is this

PS1: 100+m

ps2: 150m

ps3: 80m+

ps4: expected 80+ to 100m

All I see is when sony screwed up big time, they managed to sell over 80m but less than 100m.  As long as they do things right, they are much closer to 100m.

It is highly dependento where Sony takes the brand.

If they do completely kill off their mobile product, then the future of PlayStation's days is numbered.

If Sony merges Sony Mobile into the PlayStation division, then the next PlayStation devices should reach nmbers far beyond any previous PlayStation.

The market is changing, and android boxes, apple TV, tablets, and even PC are starting to become just as easy to play high end current games on. They also offer much, much more native software for thngs beyond gaming. If Sony does not bring word processors, health apps, banking, stock trading, e-books, e-comics, e-magazines, calanders, native email apps, video/photo/audio editing, and more to PlayStation, then the brand will fade away to the more versitile product ecosystems on the market.

So my predictions;

PS5 as a closed platform, no open app support, and no PlayStation Mobile line of products = less than 40M

PS5 with huge support for all apps and software gaming and non gaming + PlayStation Mobile products, again, with open app support, multiple configurations, all under one Sony ecosystem = more than 250M

And if sony call the next console ps now with the same feature as we know it today, then I predict the next ps5 will flop hard.

I go to sleep, so, this is probabily the lasy response today.

Any way.

Make some consideration...

PS3: bad launch, 600$/€, problem with online, problem with the graphics, strong competition from Ninty and MS, many other problems

PS4: super strong launch, hype, 400$/€, better hardware (and this time graphics), badly competition from Ninty and MS...

And still, in lifetime sales, is going to sell equal or barely more than PS3...

now, if the PS4 have the PS3 problem, or even half of that, do you think the PS4 was going to sell 80 to 100m lifetime?

Flop? No, it will sell more than every generation combined. I was just making the point that 'I think' PS5 will be an app.
