Oh absolutely, i think the chances the Switch don't become the best selling system of all time are pretty slim for many reasons.
1- It is experiencing DS high level years and is currently fighting to maybe beat DS's best years.
2-It is doing all that at a higher price and without price cut.
3- DS had already 2 revision to get there too, Switch only has the lite which doesn't give a reason to buy another system like a "pro" model will.
So yea, Switch is experiencing the highs of the DS but will also have longevity.
4-Nintendo slated many times now and will probably say in again in their next financial meeting in May, they will keep the Switch for around 8 years.
5- Nintendo doesn't have a competitor in the portable/hybrid market so they won't have to cut the legs of their console like they did with the DS and Gameboy.
So it sold around 28 millions last year, will sell around 27-31 millions this year. It has already Pokemon and Splatoon next year to anticipate a drop. Also, the fact they are releasing Splatoon 3 in it's 6th year and that it is a game that gets support 1-2 years after release just underlines the fact Switch will be the main system until atleast 2024. To reduce a big drop next year, they still have the revision card and the price cut card. So i expect the sales to remain in the mid 20s next year.
