I don't think sales will be as high as in 2016, but it will be a good year. We don't know enough about games that will be releasing in 2018, so it's a bit to early to make a prediction for that.

For PS4 I expect this year to be the peak, I also expect sales to drop a bit in 2018 not stay level though.

I think PS4 sales will shrink to 16 million this year and 15 million next year.

X1 sales could peak due to Scorpio. At the same time I don't see a single reason why PS4 is supposed to sell more than last year or the year before that. Pro, PSVR and Slim came out last year and they didn't do much.

- First holiday with good deals on Pro.

- Cheapest price yet for PS4 Slim.

- Third party hopefully won't underperform this holiday like it did in 2016 (Infinite Warfare, Watch Dogs 2, Titanfall 2 all sold poorly)

Call of Duty bundle that won't be horrifically hated (maybe)

Red Dead Redemption 2

- Stronger 1st party lineup.

2016: Ratchet, Uncharted 4, The Last Guardian.

2017: Horizon, Crash Bandicoot, Uncharted: Lost Legacy, Gran Turismo Sport, Gravity Rush 2, Knack 2, Persona 5 + ???

If $199 PS4 is coming,  then 2017 will be peak. It has the best library, it gets 4 system sellers with marketing rights in Destiny 2, SWBF2, RDR2 and their own GT:S

They will ride it out in 2018 with bundles and then announce the PS5 early 2019 at the PS Meeting.

2017: ~18-19M

2018: ~16M

2019: ~10M

By Jan 2020 ~100M lifetime sales

Of course depends when PS5 comes out, maybe it's a 7 year gen and it comes in 2020.

I dunno why Xbox could peak due to Scorpio if Pro didn't do much, who says Scorpio will do much?

I think PS4 has peaked. It only managed to sell 100k more with a slim and a pro so im expecting 17m this year. I think Xbox will peak this year because of a better lineup and Scorpio, also the Slim boosted it sales in EU by 150k last year if VGC has the numbers right and it sold really well in the second half of the year so i expect the Slim momentum to carry on into this year. I think XBO could do 8.8m

Everyone in this thread is ignoring the Trump factor.

Jokes aside, I do believe that both platforms have peaked by this point. It will be a soft peak, though. The graph will ultimately look like a plateau.

Oh wow you certainly did not convince me even though you tried hard by listing Knack 2 and a few others that will move an insignificant amount of hardware.

Good deals, low price etc.. I hear that every year. 2017 isn't special in that regard.

The Division, Battlefield 1, FFXV, Overwatch etc. sold well too. Nothing is set in stone yet. Delays will be obvious.

So like I said. 2017 looks pretty much like 2016 just without PSVR, Slim and Pro launch.

Certainly not me. It doesn't need to do much to make the X1 peak.
