Hello. I am a translator working on the games. Not much of a Pokemon fan but I will share only a few details so I don't get caught, I want to keep my job!

There will be a rockstar called Ryuki who is in Galar's Elite 4. He is a dragon type trainer and has a dragon that breaths fire and has bat-like wings on this team. Also has a turtle that is on 2 legs and has black spikes on it's back and it's red.
From what I have translated gyms are same as usual, just with the a new gimmick, but I'm not sure what it is.
2 evil teams, basically for or against monarchy
Player is neutral and has to resolve conflict between the 2 teams, but the rival joins the team supporting royal family
Legendary is 2 wolves
First town is called Bokusō-chi Town
Very story driven dialogue from what I have seen, lots of roadblocks and lots of tutorials.
