Nintendo should focus all their energy on a successful next console launch and not worry about chasing the sales record. The Switch has been a substantially more successful platform than the PS2 ever was. the DVD craze, piracy, and yearly price cuts allowed the PS2 to reach their number while the Switch has sold some 140million without a price cut while selling over a billion in software at full price. All this while coming off the failure of the Wii U and going up against the PS4, PS5, Xbox 1/X/S, mobile gaming, PC gaming, and the Steamdeck. PS2 essentially had the market to themselves.
The Switch will go down as the most successful gaming console of all time wether or not they get the sales record.
