What most people don't realize is that the OP will have to create a new tier for Switch.  It has SS for DS and PS2, but Switch will be SSS tier.

Where would SSS tier begin? 200 million units? Possible for Switch, but not a sure ting.

There is still a long way for that. If Nintendo announces Switch 2 next year and releases it in ~2 years (backwards compatible to Switch 1 plus new games exclusive for Switch 2), Switch 1 sales will probably go down after the announcement.
