This is the same Nintendo that in 2018 released Donkey Kong Tropical Freeze on Switch (which wasn't really a remaster but more of a port with slight changes) for $10 more than it launched on Wii U and was even a Nintendo selects title on Wii U at that points and permanently cut down to $20 so they ended up removing it from the Wii U eshop!

Then just two years later removed Pikmin 3 from the Wii U eshop which was $20 at that point so the port of Pikmin 3 on Switch wouldn't look so pricy in comparison:

I do think they ended up putting pikmin 3 back on the wii u eShop after some time tho.
If they ever remaster Luigi's Mansion 1 if it's either the gamecube version or 3DS version it will almost guaranteed to be another $60 purchase
