so these chinese leaks seem to be a mash of info from different sources. I would love to see the final evolutions of the starters being those in the picture but if so i don't want to see yet another fire/fighting starter. Yes, the wrestler tiger looks cool but i had enough with the fire/fighting starters. Heck, the only pure fire starter final evolution is still to this day typhlosion. I want more pure fire starters or if it must have a secondary type i would love dark. The archer owl looks the coolest and the syren is such an unnexpected turn for popplio's clown motif.
Rockruff's evolution being an werewolf can still be a thing, given the description on the official site. as for marshadow's unique typing, the only uniqueness i can see is either fairy/dark, fairy/dragon, fire/ice or fire/grass. with a name like marshadow, the only type fitting is dark/fairy.
the only thing that makes little sense is the non existence of gyms or a league. there's seemingly no referencial buildings that can be identified as gyms but i would be shocked if they ditched such a traditional format. It's the same as the starters and their base types, a professor that gives you a pokedex, a rival, an evil team (or two) or HMs being unforgettable (which is a thing that just needs to change but they refuse to).
