I don't know if there are only retarded zoomers here or what. Yea, it is the fastest selling console but will it keep it up? What is happening is a tale as old as time(at least for me).
Nintendo already did it three times- upgrading last gen console to sell it again, it backfired 2 times(and I guess 3ds case will be repeated, but who knows, maybe cattle now is dumber)
>gb to gba- moderate success in console sold and software but still decent
>ds to 3ds-very strong initial sales of console followed by very big drop in game and console sales, had to change price of console 2 times and drop the price of games
>wii -wiiU - complete disaster due to shit marketing.
Speaking personally, I have a switch OLED, bought it only for exclusives that I don't see being done now(astral chain, both bayonettas) don't care as much now after playing them(fire emblem). The only thing that would maybe make me buy new switch in future is new game from monolith, but even then the prices of games are abhorrent and nintendo rarely drops prices.
