2017 15-20M
Lifetime 65-80M

5 million for 2017 unless they overcome the undershipping problems by the holidays, in which case 6.5-7.5 million.

Lifetime: 30 million low end, if they don't lower the price by holidays 2018 and if the software lineup doesn't shape up. 70 million high end with hd Pokemon, true combining of the home console and handheld libraries, and aggressive price cuts.

It will sell more in 2018 than in 2017 due to being on the market for a full year, not having the undershipping problems of 2017, and having more games available.. The year the next pokemon comes out will be its highest selling year, and it will be downhill from there

If handled like I fear it would be - 25m or less

If they have a really big shake up and actually watch the market and see what people are willing to pay and get software coming out at a decent pace - 50m lifetime

I really think Nintendo think that the idea is worth far more than it actually is, online fees, 70e controllers, no pack in software, so much bad ideas to get people to buy the system, after that show on the 12th I most certainly went from a "Day 1" to a "Maybe some day if they prove they're not going to Wii-U it"

I can't see it doing well, to be honest. I find it unattractive as a home console and too expensive for a handheld.

I'll be pleasantly surprised if it sells more than 35 mil. lifetime.

Good in Japan, average to bad in North America, and makes the Wii-U look like the Wii in Europe and elsewhere.

IDK as for numbers man, maybe around the N64 or a bit more, being a bit optmistic here?

Mind you, I said 40m for the PSV and the Wii-U a few years back.

I would say 30-40 million units, and I'm being generous here. It's a somewhat novel idea from Nintendo. But what they need is to dish out the games, quickly. Maybe then it'll sell around 45 million units.

More than the Wii U, less than the 3DS.

The rest depends on the price development, software support and future revisions.

If they manage to shrink the device to Vita/3DSXL size & weight, enhance the battery life and lower the price in 2 or 3 years (as an additional option to the bigger model), they could win back some handheld fans who don't want a clunky hybrid, it could exceed 3DS numbers.

Sell more than 3ds, since it will capture the 3DS audience, WiiU and some of the mobile crowd that played Pokemon Go and Mario Run.

Don't forget that once Nintendo launches Pokemon for the Switch, somewhere in 2018, it will be a massive sucess, if it brings Pokemon Go functionality with regular Pokemon Rpg

Lifetime : 50 mil
1st year : 3 mil

It really doesn't matter what people "predict". The Switch is a wild card, anything can happen. Of course that isn't going to stop the lucky guessers to claim they knew all along and have no Idea how anyone else expected any different.

So my completely arbitrary guess is that is going to be one of the few systems to move past the 100 million mark.
