GameFreak loves using old Pokemon designs with new features to create new Pokemon or forms. We now have Megas, Regionals and more. Each generation brings something new based on old Pokémon designs, so Generation 10 will likely do the same.

I'm just wondering what the next logical step would be and I've come to the conclusion that next generation regional fakes will get probabably new evolutions, just like Galarian Farfetch'd got a new evo in Generation 9. New Baby Pokémon for Regional forms would be dope too, imagine a new duckling Pokémon that evolves into Galarian Farfetch'd.

I am also curious whether the new cross-gen evos from Paldea, will always be available as normal evolution, not like these from Hisui.
