This year should be the Switch's peak. Next year Switch will be on the down swing. Nintendo consoles typically drop faster than Sony's consoles, but due to the Switch's popularity, it's unique place in the market, and the proposed software lineup (heavy hitters like Zelda and Metroid) I think it'll be slower. 20-23M is my guess. The year after will probably be under 17M.

What is the projection for this year?

Through 46 weeks of VGC tracking it is ahead of everything, including 07 and 08 DS which are the two highest years on record.

30M for 2020 is the safe guess, but honestly it should have a bigger December than 07 NDS had (08 DS went higher than 07 in December, despite lagging behind the rest of the year - NSW should be in that ballpark).  So maybe 31-32M is possible.

Voted >25M. It will match or pass this year if the Pro revision happens and it is counted along with the rest of NSW sales.

It's going to be >25M... I mean this is a joke poll right?

They've only started to enter the Chinese market and it seems they are really going to see a lot of growth there, already catching up to the PS4.

They only launched Switch in 2019 in China. It's the biggest videogame market so if Nintendo can carve out even 5% of the overall gaming market that would translate in millions and millions of consoles. Their games don't have problems passing censorship and most Japanese 3rd Parties are already in relations with Tencent or other local Chinese companies for localization and marketing. 

I will just leave this here: https://gamrconnect.vgchartz.com/thread/243789/furukawa-other-regions-grew-by-a-huge-152yoy-driven-by-asia/1/#8

I mean, I do agree with you but so far the poll is showing that there are people who think otherwise, so I think that right there justifies the existence of the options on the poll.

I mean, it's probably going to match this year, come close to it, or even do slightly above it. It could end up like the Playstation 4's 2018 compared to 2017, where it basically shipped the same amount, but fell short by a few 100k (in the Playstation 4's case, because it was overshipped in 2017's holiday quarter, iirc), but will also have even better software sales, leading to a healthier year overall, and probably it's peak year.

I expect about 27M, so >25M

Disappointed that I'm the only <5M vote so far.

Would love to see Switch do 28 or 29 million this year and have a strong hold next year and still do 25-27 million. It's certainly possible if 2021 has price cut, new model, zelda collection, pokemon remake, botw2, great 3 party lineup, and a few other big games, along with what is already confirmed.
