The Wii experienced a baby drop of 2.3m down to 22.52m in 2009 from its peak of 24.82 in 2008.  It's first significant drop was a 5.33m decrease to 17.19 in 2010.  If 2021 is the initial baby drop from its 2020 peak, then I don't expect the Switch's first significant drop to be greater than the Wii's 5m drop.  Of course it all depends on how many Switches Nintendo is able to sell by the end of this holiday season.  But, I decided to be bold and went with the 22-25m option in the poll.

22-25. It will have an insane amount of exclusives and massive ones. It will have a full year with OLED and should be more in stock. If sales drop too much they could still cut the price and i doubt they will let it die like that by losing 5-6 millions compared to 2021.

I voted 18-22m, but I expect it to be at the higher end of that, probably around 21-22m. I imagine chip shortages will continue to cause difficulty with producing more units than that, and considering sales have already likely peaked, I can't see it going any higher than this year regardless of the stock issues. Still, Switch continues to hold its momentum, and has a ton of major releases already announced for 2022, so it'll still do really well.

The Switch has been very unpredictable. 2022 could be as low as 18 million units, but could be around 25 million as well depending on supply and demand.
I voted 18-22 million and I think right around 20 million will be the total. PS5 and Switch will be closer in 2022 because Switch will sell less compared to 2021 and PS5 will sell more.

25.5

I voted 22-25m. Demand for OLED will still be going strong for at least the beginning of 2022 if not the whole year. More importantly 2022 is going to have an incredible year for software. Switch sales are going to stay strong.

I think it will be in the 22 - 25 range, possibly closer to 22. Obviously, I expect 2022 to be lower than 2021, but I think it should still be above 20m. I'm of the opinion that we will get another Switch model in Holiday 2022.

I think it'll do around 22 million, so I voted 22-25 million.

It's gonna be a ridiculous year for software, plus OLED model will start having better stock. I would guess the OLED model would drop to $300 as well, with the original dropping to $250 (and maybe getting discontinued).

Software is Pokemon Legends, Splatoon 3, Kirby, presumably a DK game, presumably a Metroid Prime remake/remaster (1 or trilogy), advance wars, BotW2, new Mario + Rabbids, presumably Bayonetta 3, wouldn't be surprised to see (read: hoping for) a Zelda WW/TP pack, probably some other moderately big games, and I gotta think maybe a new 2D Mario game would hit as well cuz 2023 seems a little late to release a game as big as that. That's a ridiculous year. Multiple 10 million sellers and maybe even two or three 20 million sellers.

That software lineup on top of possibly a little bit of a hardware price drop and I'd be surprised if Switch doesn't get around 22 million. It is certainly passed its peak now and will drop but next year looks insanely strong. So a drop from 24/25 this year to 22 seems reasonable.

BOTW2 alone will boost it more than that. Then we have Splatoon 3. Mario vs Rabbids 2. Advance Wars Rebootcamp. New Kirby and Bayonetta. So it will still have games that people will want a Switch for.

I don't think Nintendo will be as limited component wise as the PS5 and Xbox Series will be next year. That said, I still think they are going to be in the low 20's high teens for sales. Software looks good, so I'm going to be positive and say it'll stay above 20M, but I do think it has a real chance of dropping to 19M.

This is mostly due to saturation though. If it stays close to 2021 numbers then I think Switch has a shot of being the best selling console of all time. I just personally don't think that's going to happen.
