It can go either way, but unless many upgrade from PS4 to the Pro version, I doubt it, as slowly there's some saturation setting in.

@Bolded: Again, you show that you don't seem to understand that hardware always comes at a price. In this case, the 500GB SSD alone would break the 150$ pricetag by far, especially since it will have to come in M.2 format (or soldered on, making it unupgradeable in the process) to fit into the small case you're proposing. Plus, as cheap as it might be, I doubt it would sell well without the possibility to play the games on discs.

@Italic: Won't come until next year minimum, as it will need the 7nm with stable yield rates to be able to shrink down the main chip enough to create a slim version of that chip. Unless Sony wants to risk overheating a lot of units, RROD anyone?

@Undelined: Hahahahaha

Sorry I laughed out loud when I read those. Tech ain't there yet to allow a PS4 portable (you could make it - in laptop size that is. Raven Ridge at 15W TDP ain't far away anymore in GFlops from the PS4, at 20-25W it should be feasible), let alone PS4 phone

Well yeah, PS4 still costs 300 like you said so there's plenty of room for price cuts.

Edit: Plus 2018 is looking great for games on PS4 (barring delays)

500GB M.2 Drives are already available to consumers at $129.99  - $149.99 on the low end. Flash prices are supposed to start dropping very quickly over the next decade, while capacity sky rockets. By late 2019 500GB of Flash Storage will be ~$50 for cinsumers and even lower for a company like Sony. Digital is going to be 60% or more at that point, and casuals have no attatchment to physical game. These are the Netflix, Spotify, Youtube people of the world. They just want cheap and simple.

I have PS4 Pro Slim in 2019 predictions.

The Portable is way more possible than people are making it out to be. By late 2019 a 15W APU based on 2nd gen Ryzen and Navi using 7nm fabrication will be at PS4 Pro levels.

I’m inclined to believe 2017 was the peak year and 2018 will see a small decline. PS4 sold 20.2m in 2017. I see it selling less of about 17-19m just on the basis of Switch and the console getting long in the tooth. Same goes for 2019. Probably another 16-17m. Of course I could be wrong but I don’t see it keeping these kind of sales up. The $199 was already used so I don’t think it’ll have that big of an impact the second time. It should have stayed $199 imo. But overall 2018 will still be a very good year for PS4. Of course I could be wrong but I don’t think I am. Feel free to bump this comment this time next year. :)

The problem to that is that the production capacities for flash are by far insufficient for the demand, driving the prices up instead of down. Also, next decade? That starts in 2020, so only in 2 years. By late 2019 500GB won't cost just 50$, not for consumers and not even for companies unless the production capacity has been massively increased in the meanwhile (and the outlook on this is sadly grimdark)

Flash is slowly reaching it's practical limit in shrinking. The smaller the chips, the shorter the lifespan of the flash memory cells. At 7nm we will most probably cross below 100 rewrites per cell. At that point Flash can't be shrinked anymore lest the risk of failing shortly after sale is getting too big, even with huge storage spaces. Hence why there are several successors in the works, but they are all still much more expensive than Flash. Only Intels 3D X-Point (marketing name: Optane) made it to commercial level yet, and with about 5 times the price of Flash memory.

Come on please, get realistic with your tech previews. Even at 7nm there's no chance that Ryzen 2 + Navi can reach PS4 Pro levels. I could see it reach 2500-3000 GFlops (which is already a 50-70% increase over what we have with the upcoming desktop Ryzen 5 2400G). In the "Playstation Switch" Thread I stated that this would be possible by 2020 - and you want a PS4 Pro Switch by late 2019? Not a chance in hell. It's not because it's called 7nm that it's actually twice as small and double as performant as 14nm, those times are long gone. At best you can get a 40% increase outside of clock speeds and IPC increases, so my 50-70% can be seen as optimistic already.

True but was switch not heavily supply constrained for much of 2017? Nintendo even stated late summer I believe just they were gonna be ramping up production a bit more. It also won several months of npd last year despite the supply shortage. Not to mention the switch had no good deals in America this Christmas and was full price against a $199-$249 PS4 and $189 Xbox S. If memory serves, PS4 also didn’t have any good deals in 2014 other than a gta5 bundle at full price whereas Xbox was heavily discounted with the Assassin creed bundle and beat PS4 handily. 

Personally I see switch having a much better 2018 now that they have a more steady stream of units hitting shelves. 

Very true. But here’s my thing. Not even ps2 was up in its 5th full year which you’re thinking PS4 might be and others are too. The only consoles I think were up YoY were maybe the Wii or 360 with Kinect. But PS4 doesn’t have anything to spur sales to a greater threshold like Kinect did. 

So even though I predicted a decline from 2017, it wouldn’t surprise me if PS4 proves me wrong. I’m hopeful it does. I’m curious how close it comes to that 155m sold by its grandpa. 

If Ps4 in 2018 drops to 17M it will be very improbable for it to hold to 16-17M on 2019. After the peak the drop is more probable than flat years

I guess no one necroed this one either.
