those who are into Pokemon, for the extra frame rate

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.
