For what it's worth, XBO X got me excited about Xbox. Xbox Game Pass with 1st Party games day 1 got me to buy XBO X. Sony's lack of support for the PS4 OS, Apps and Services got me to buy a XBO S for the Bedroom. Finally, getting my old Windows Desktop back from my Brother after he upgraded from it, combine with Game Pass on Windows, lead to me buying a new AMD based Windows Machine.  

That is just me, but Xbox sales have been on the rise. Mat Piscatella said XBO has the higest growth of the big three, and XBO X is doing phenomonally.

On top of that, I have heard many people talking about going back to Xbox over the last few months. 

I think Microsoft is doing some incredible things right now. It may not be enough to overtake PS4, but it is definitly setting them up to take a shot at outselling PS5. Microsoft is closing the gap between making every Xbox a Windows Device, and Every Windows Device an Xbox. I know many in this community mock that Xbox 1st Party Games going to PC, but in reality, it makes every PC and Xbox, which means you are not limited to how and where you play your games. In the long run, if Microsoft means game anywhere, at any level, while PlayStation is you play the games we allow you to, on this box connected your TV. Then Microsft is going to wipe the floor with Sony in the long run. 

Remember, it took PS4 4 years to get where it is. You were kind of jumping the gun with how fast things would swing. Change takes time. 

But you can be certain that the 1 year it took to launch on PS4 and Fortnite coming earlier did a good impact on total sales PUBG can have on the platform.

But only like 50m of those players are on Pc + Console.
The majorty of those 400m players (~350m ish) are from Smart Phone users, from like China.

I think in the west, on pc and consoles it does look like fortnite killed it.

And exactly why, does smartphone and China not count? What are you trying to say here? 

He might just be counterarguing with Jason1637 , but in this thread was about ONEX and PUBG's impact on the PS4 versus XBOX console sales race,so they have no relevance here.

Jason and JRPG were discussing PUBG vs. Fortnite in general. 

Yes, of course. You're absolutely right about that. However, it's stil far, FAR from being dead.

Basically, the One X bumped sales up from the rather disappointing levels they were at in 2017, and even delivered the XBO its best-ever Q1 in 2018 (in the U.S., at least), but wasn't enough to make 2018 as a whole the XBO's peak year. And the only software to significantly impact XBO sales was RDR2, which gave a noticeable YoY bump for October alone. Certainly an improvement, and solid sales overall, but it didn't take the #1 spot for the year in the U.S. Given how similar the PS4 and XBO are in terms of capabilities and game libraries, it was always highly unlikely that the XBO could have turned itself around and consistently beat the PS4 on a monthly basis in the U.S. Inertia is a cruel mistress, and we almost never see a system experience some massive turnaround after a slow start (the Genesis and PS1 are the only exceptions).

Yeah. That does certainly seem to be the case. The XBO had only a small YoY decline in 2017, but that decline accelerated starting in June when the X1X was fully revealed:

Interestingly, while the XBO was up YoY for November thanks to the X1X launch, the XBO was still down YoY in December. Supply issues, maybe? The X1X did help the XBO to have its best-ever Q1 and second-best Q2 in 2018, though.
