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.
