PS4/X1 sales to peak this year and keep it for 2018?

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.

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.

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

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