Wow. Very good launch numbers for Switch and Zelda! So at lest the reports of Nintendo upping their launch shipment where legit.
And at lest in Japan it's not slowing down at all.

10m by end of fy 2017 seems a bit on the low side, though. I'd have thought more along the lines of 12m.

Planning on shipping 10m units this fiscal year? There goes a ton of overblown predictions.

Just like them saying they were planning to ship 2m units in March limited its sales to 2m...right?

You'd imagine post-launch predictions of future success would be easier to nail down then the 2m forecast they made for launch even before their pre-launch events.

But yes I'd imagine a forecast of 12.74m shipped by the end of March 2018 heavily indicates people predicting 15m+ (or even 17.5m) sold to consumers are reaching too high.

Well, i wasn't pointing it out in-defence of those people eho predicted those numbers, rather that they're willing to ship more if the demand is there, as they clearly did in March, so in theory it can do the numbers of those predicted. I do however think they will probably end up at around 12-13m, though, you never know

Well after failed Wii U and 3DS predictions, they are definitely more careful for their predictions and going for lower estimates. In any case around 13m after 13 months on market would be great start.

How much exactly Wii U had sales in its 1st year?

Nah, happend all the time during the Wii and DS years. If sales stay high they'll increase their prediction to 11m next quarter. Then 12m the quarter after that... 

First 12 months had about 3.8m sold for Wii U.

It is already in stock on Amazon.

3.91M in the first 11 months.
