Personally I had no desires to buy any new consoles to play new Pokémon games after the GameBoy SP and FireRed/LeafGreen, but I try to keep up with what is happening in the Pokémon world. 
Since there were no games for me to spoil I've been keeping up with all releases and discussions about the new games. 

Bulbepedia isn't updated with information about the new Pokémon yet, they only have a list of what is available in Galar, so I might watch some of the new anime.
