Which is easily explained by the PS4 having 2.9m units on shelves at the end of 2017, and the Switch having stock issues in 2017. Switch would want to ship more then they could sell in that quarter to finally get a healthy amount of units stockpiled on shelves for sale, and Sony would want to ship less to reduce excess stock.

We need Nintendo sell through numbers, otherwise we can't know much. They release shipped hardware and software every quarter, but that's not telling enough.

You went from global to US back to global, how about you stick to one?

It may win some, while losing others and who knows what the end of Sept gap will be.

I could have sworn we already had this talk.

During the presentation for the quarter ending Sept 30, Nintendo said global sell-through was over 7 million.

Nintendo gave a press release in mid-Dec saying sell-through was over 10 million.

During the presentation for the quarter ending Dec 31, Nintendo said sell-through had surpassed 13 million excluding some regions such as Latin America & parts of Asia.

They gave 3 separate sell-through updates in a 3 month period.

Do you expect Switch to win many weeks world wide in the mid year up to the release of Smash? If so, what will drive those sales? Mario Tennis maybe? Winning the US means it's more likely to win world wide, which is why I asked.

I went looking..

Found it, thank you for that. So lets say 13.2 million by January? Best thing to do from now is wait until Nintendo announce 20 million sold through, which they likely will. At that point the Switch will have sold 6.8-ish million units in 2018. Same as when PS4 sells 80 million it will have sold 6.4 million in 2018. According to VGChartz the PS4 is already on track to do that early into June. But at the current rate Switch is going it's looking like it might take until August or longer. This is of course if VGChartz isn't overtracking PS4 and undertracking Switch, which is possible. Sell through announcements are the only real way to know.

The current gap is only reported by VGC. It's meaningless until we have more concrete figures. I suspect the difference between PS4 and Switch sales is exaggerated on VGC and in reality the gap is much smaller. You can read my response to Barkley below - the concrete sales sources available makes VGC's estimates hard to believe.

VGC would have us believe the PS4 went from having 2.9 million units on shelves at the end of 2017 to 1.4 million by the end of this Q1. Do you think the PS4 sold 3.94 million in Q1? Because that's what VGC is saying right now. About 971k came from the US, as per NPD, while (an abnormally high) 720k came from Japan, as per Media Create. That still leaves us 2.25 million short of what VGC suggests for Q1. Personally, I think that's too much for Europe and RoW to cover...

That may well be, hold on to that possibility! But also just wait until Sony announces 80 million. If it's not in June, then VGChartz is overtracking PS4.

Looking at VGC data last year, PS4 did 1,010,519 units in the US, 1,742,809 in Europe, 514,757 in Japan and 786,241 RoW bringing it to 4,054,326 Globally by March 31st. This was after taking into account the 7 million sold in 2017 by June 11th. Looking at how close the US numbers are this year, why would worldwide be much different? Especially with higher Japanese sales because of MHW.

To me, looking at 2018 NPD numbers in Q1, 3.9 million worldwide seems perfectly plausable. PS4 actually sells outside the main markets. It's already the 3rd best selling console of all time outside of the US, EU, and JP behind PSP and PS2.

Okay, so Switch "dominated" in December with 4.05 million units sold compared to 3.55 million PS4 units sold. A difference of 500k or about a 53.2/47.8 percentage split in total units sold between Switch and PS4. That is domination to you?
