I'll just say. Make a believer and reach 25M on 2018 =p

I think there is a very good chance of PS4 selling more in 2018. Looking at what is coming already, and the possabilities of price cuts to PS4 Slim and PS4 Pro, I can see Sony shipping 25 Million units in CY2018.

However, I believe 2019 will be the peak. We know for sure that a PS4 Super Slim is coming, and it should launch for $149.99. There should also be a PS4 Pro Slim for $249.99. Then we have the wild cards, PS4 Premium, PS4 Portable, PS4 Phone, PSVR Pro.

I believe 2019 will end up being the first year, with major 3rd party AAA PSVR support. With PS4 Super Slim + PSVR $199.99, Sales will be absolutely insane regaurdless of Premium, Portable, Phone. I think Sony could break the 30 Million shipped mark in 2019.

Outside of gaming, I believe the PS4 Super Slim will come in a Digital Only form factor with 500GB of Flash. With no Blu-ray Drive and no HDD, the thing will be roughly the size of Amazon Fire TV, Apple TV, and Roku boxes. I also think they will put HDMI 2.1 in it allowing for 4K HDR video content. This will be combined with 4K HDR TV using Hybrid Log Gamma on PlayStation Vue, and a huge push in the Set Top Box market. This could even turn into a thing where they offer PS4 SS for free with 3 months of PS Vue, or at a substantial discount.

This is just based on what we already know. We still have 2 years worth the trade shows, and partenerships. The more the PS4 sells, the more 3rd parties, gaming or otherwise are going to want to be on the platform.It is going to be an awesome ride.

Hard to say. If they go that route, then PS4 sales should remain blazing hot. On the other hand, if we start hearing about PS5 in Q3/Q4 2018, then PS4 sales will likely plummet. One thing is for sure, we will know one way or the other by the end of this year, because whether PlayStations next device is coming in 2019 or 2020, devs will be talking about it 18 to 24 months before hand. With 7nm chips being ready in by Q4 2018, something is definitly cooking for release.

I expect some controlled leaks that point heavily in whatever direction they choose to take, because it can have dramatic sales implications.

Well it is until now, if 2017. will be all time peak PS4 year, we will see this year beacuse IMO 2017. or 2018. will be peak PS4 year.

2018 has a chance to do 25 million if sony plays there cards right.

I enjoyed reading this. Much like a riddle.

Resogun.

watching the 2018 games, i think it will be this year, never saw a better line-up

Lineup looks weaker this year than last year.. so in terms of software I doubt it. Unles something massive comes along ofc.

As for hardware... if they sell the hardware at a great price for a long period of the year,, sure.

Yep a price cut is possible and it could enable the peak on 2018. But as you said it isn't certain, but on the SW it may be one of the best years so far.
