Considering that December they sold almost 900k just in Japan. Putting the 15M as a rough estimate, it is very plausible for shipments.

And I got congratulate this piece of article. So many feathers we're ruffled here

Nintendo has officially announced 4.8 million sold in the US. Considering all of North America is a little higher than 1/3 the total Switch sales, these numbers now sound more accurate.

Lets see

USA-~4.8m

Canada is about 10% of USA and lets say Latin America is half of Canada.

Americas-~5.5m

Japan-~3.3m

"Others has been right in the middle over Americas & Japan at each quarterly report so 4-4.5m.

Global sales are likely in the 13-13.5 million range at the end of the year.

Sounds about right for this number to be shipped

Here are the sell through numbers at the end of Sept

Japan-~1.8m
USA-~2.3m
Global-~7m

End of year sell through

Japan-~3.3m
USA-~4.8m

At the end of Sept, Japan+USA made up about 60% of global sell through. Assuming that remains the same at the end of the year than we are looking at about 13.5 million sold globally.

Not so sure about that. US ratio will increase while Japan and others has decreased.

Best guess for me is 13.5 million sold, 15 million shipped. Numbers seeming more legit by the minute.

Hmmm, I wonder what their source is? That's pretty crazy and means they've already zoomed past Wii U in well under a year, which is nuts. 

I suppose, if Nintendo did mention selling through over 10 million on Dec 10th, it's feasable they've sold 3-4 million more in the month since then worldwide, being the holiday season it's possible - and the 15 could be shipped as of January, meaning 1-2 still sitting on shelves which sort of makes sense.
