It would probably take Switch 2 releaseing late 2024, maybe 2025,.... and a price drop to reach that.
It could happend, however I think Nintendo likes profit, more than it cares about record setting.
100$ price drop next month announcement on Switch, would probably do good things for sales.
A full year of that, and I could see it happending.
I said the same thing with the PS4.... (not beating the PS2 in sales) (but with pricecuts needed last part of gen)
Sony went for profits on hardware sales margins, rather then trying to sell more units.
Its end of life cycle was abit dissapointing... it should have been abit cheaper, to push more units.
Even this year, I hope they lower prices of the PS5 abit.
Keep trying to push those 20m+ sold though years, so you build up a solid userbase, and try beating the PS4 sales.
