I voted 25-27.5m. We don't have all the sales numbers for the current calendar year, but it will probably be somewhere around 28m. I expect 2020 to be the peak, but 2021 will only have a gradual decline. And in fact I think Switch will continue to have gradual declines until its successor is released. Nintendo still has lots of room to offer price cuts and hardware revisions. On top of that third party software for 2021 is going to be far better than any year for Switch so far. First party software will continue to be at least as good as 2020 for several years. Put all of that together and I only see mild YoY declines for Switch each year.
Bonus: Most anticipated game is BotW2.
curl-6 bet me that PS5 + X|S sales would reach 56m before year end 2023 and he was right.
My Bet With curl-6
