A lot of players and local venues prefer PS4, PS5 and PC for fighting games. If you have licensed PS4/PS5 arcade stick it should work on all three of these platforms. Unlicensed ones might not work with PS5 games. Switch is mostly just for melee.
That being said game key-cards seem largely inferior to physical versions on other platforms even if you likely have to patch most games these days anyways.
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.
