Between 130-140 million. 55-60 in Americas, 30-35 in Europe, 25-30 in Japan and 10-15 in ROTW.I currently own one system but I'm not sure If i'm going to buy another one in the near future although, I'd like to live the lite experience at some time. I'm really optimist for the sales of Switch.

EDIT: I miss your Kim Possible banner.

Honestly these last few months have convinced me its gonna end up closer to the DS than the Gameboy. The Switch is in higher demand than ever and I could see it doing incredible numbers both this and next year.
Currently I'm thinking somewhere between 140 and 150 mil.

Huh, totally forgot about even voting in that but apparently I had the same estimate. Can't remember what my reasoning was at all.

At this point I'm far more optimistic about Switch's future. It may be peaking now, but whereas many seem to believe it'll still fall off and stumble towards it's final years, I feel they have a lot of big hitters preparing for the second half of it's life, that'll help sustain high numbers for a while.

The fact that right now Switch is coasting on the sales momentum of Animal Crossing, a beast that no one was prepared for, epitomises how Switch has been able to blow expectations apart on several fronts.

If there was ever the time for more people to become bold, it's probably now.

I'll still put it just at 130.0 - 139.9 million. I'm feeling 135m is good for now. 5m more than PS4, which I'm guessing will sneak over 130m.

Bonus answer: One, and one (unless there's a Switch Pro or something crazy).

122.5m, The Switch will buck the trend for nintendo systems by having a longer tail and not nosediving in sales after year 5.

110 million. Beats PS1 and Wii but falls just shy of Gameboy, ending up the #5 best selling system of all time.

130 million.

70 million by the end of the year, 90 million next year, 110 million in 2022, 125 million by 2023, 130 million by 2024

I can see it top 120M, I’m not confident enough in it’s legs to go up to DS territory.

Bonus answer: One. Will remain one.

More than the PS4, so 130M-150M.

I don't understand all those who say 110M or less. There's simply no reason for the Switch to crash like the Wii did, sales are way up and don't look like they will come down anytime soon, so most probably this year's sales will be up from last year. This would put the console already at over 75M, and over 10M more than the Wii had at the end of 2009. The Switch would need to crash even harder than the Wii did just to be able to stay below 110M at that point, and that simply won't happen. The reasons for why the Wii crashed so hard are simply not given for the Switch.

Bonus Question: Just one, though I possibly buy a new one when a more powerful model comes out, giving mine either to my cousin or my wife.

Around 85 million

100-120 miilion.

Bonus question: I have one Switch.
Bonus info: I am one of the few persons that only plays in docked mode.
