Wouldn't have expected anything else. The two types of people I've mostly seen buying the Switch 2 are those who are really into Mario Kart and those who are into Pokemon, for the extra frame rate.
Neither of these groups is known for buying 3rd party games - at least not the ones I know.

Not just Pokemon, I am sure there are many who where hoping for Switch Pro before Nintendo crushed their hopes and dreams with Switch OLED. People have been testing Switch 1 games on Switch 2 and most of them seem to run on very stable frame-rate on Switch even without an upgrade pack.
This will lead to stronger console sales but not necessarily to game sales at least not in the short run.
Yup! 🙋♂️ I'm only here (having a Switch 2) for the frame rate bump (which I thought I'd get from buying the Switch 2019, or the Switch OLED), as well as the GameCube games and future Mario and Zelda games. Nothing else.
