I think it's unfair to put it on the same level as Nintendo titles when many PS titles were sold in bundled with other first party games together with discount and lower price than Nintendo titles.
It's not a bad thing since Sony is very generous and aggressive with their sales promotions and discounts, while Nintendo Switch only getting overpriced special edition bundle that made no difference than buying a new console plus a new game as the bundle price was around $359.99.
MK8D limited bundle was the only discount bundle from Nintendo and still expensive than Sony Playstation official bundle. There were few retailers exclusive bundles with similar price.
If games like BOTW, Smash Ultimate, Pokemon Sword and Shield, Animal Crossing, Super Mario Odyssey, MK8D, SMP, and etc were receiving the same bundle treatment as PS bundle then the current ltd sales for those games are likely 10-15 millions higher. Those games are still retaining the same original pricing as when they were released on the market while PS games are already getting official price drop for multiple times.
