Older Pokémon carried over?

What do you all think the possibility of Winds and Waves carrying over some Pokémon from Sinnoh?

I’m not sure how Game Freak handles bringing in older Pokémon into new titles so I’m curious what you all think.

To be frank, the Shinx line are my favorite Pokémon and I’m wondering if there’s a chance they’ll be in this one.

Thanks!
