So PS4 keeps slowing down this year. Yep no pricecut will take its toll. Will they cut for next year to cushion it untill 2020 PS5 arrives?

I price cut will help, but not by much. I think we're going to see the PS4 baseline noticeably decline in 2019. This year will finish slightly above 2015-2016 levels. Next year, we're going to see the baseline go back down to 2014 levels.

Call me optimistic but I think that if they drop the price low enough ($250-350 for PS4/pro and $230-400 for X1S/X) both machines will be able to match this year's numbers.

1 X clearly doing the work for the Xbox. It's likely to be flat or just over YOY in its 5th year. Switch growing quite well. Expect December to be at least as good as last year.

I think PS4 could hold it's sales mainly due to it's superb 1st party offerings this year. Next year won't be able to keep that up and sales will go down. The fact that neither the Switch or the Xbox had any exclusives throughout most of the year that could hold a candle against them meant it faced rather weak competition, too. Next year doesn't look like Nintendo will have everything around the holiday season, so PS4 will face much stiffer competition throughout the year, and the age and saturation will start taking their toll.

In short, I believe PS4 sales will go down even with strong pricecuts. However, those (and their timing) will decide as to where the sales next year will end up - I expect somewhere between 12-15M

If they cut baseline to 199 next year they can certainly keep it up, but Sony seems to be satisfied with current sales level at larger profit margins.

Yes. Right now a $50 price drop won't stop the decline. It may not even make a difference. Whats needed is a $100 price drop.

At $199..... it could very well keep the pace of this current year. I guess its left to be seen if sony would but i doubt it. If somehow they only manage like 500k in december this year that would push them t make that price cut in january..... but thats not going to happen.

Even more because MS have stopped the aggresive price cut as well. So probably PS4 is pretty much still above expectations (as seem from their projections needing 2 revision up already)

I see they have updated the X1 and PS4 numbers for 2017 which puts the X1 right back to being down yoy.

But I wouldnt rush to do the updates on the chart just yet.  I have a feeling that there are some more updates incoming for 2018.

December 1st Numbers have been added
