Yes I would say 18M at least.

Surprised to see xbox beating Switch in the US

I was expecting them to be very close, but still Switch on top; I was wrong.

that's right, all 3 got good numbers

2018 has been an amazing year for PS4, which seems to be unstoppable even after 5 years...and it's not the whole story, as 2019 will be amazing too with all the AAA titles supposed to be released next year and a likely price-cut.

Xbox did very decent compared on how far they usually are behind the others saleswise.

And i really think the following gen is even going to get better, if you think about it then it kinda has the right setup to it.

Sony wants to keep momentum going and let that momentum overflow into nextgen while still partly keeping it in the current and you can expect Microsoft to do everything they can to go back to the xbox360 popularity and to do that they need to get a lot more competitive with Sony on the exclusives and we have seen them prepare for it in the recent years or at least we can say that we have seen the signs for it.

Sony should also predict Microsoft competitiveness for next gen so it can be a possibility they also try to boost exclusives.

And Nintendo is a case on its own competitors wise and does not really have to share its market with the other ones as it has such a coexisting nature with its exclusives and focus/audience but now with the switch they on themselves are also in an uprising again and i am expecting them to boost and hype it even more with an upcoming new switch model.

Compared to last year: 3DS is down, PS4/XBO are about equal and Switch is up.

500k more sales YoY, that's huge
