>>276707971st paragraph: The posted trying to explain where the leak comes from, nothing important here.
2nd paragraph: There's no gym in Sun/Moon, the main plot is the professor trying to guide protagonist to establish a new league in Alola.
No pokemon league, so of course no gyms there. The gym leaders are replaced by captains.
3rd paragraph: And instead of four elites, there are "island kings" for each islands(maybe they mean the kahuna in the trailer?).
After the league being set up, the four elite will be there.
4th paragraph: The new bracelet enhances all skills(note: I'm not sure what does 技能 mean here, it can be translated to skills, abilities, even moves)
The crystals, like the one in the logo(see japan logo) can be installed into the bracelet. And similiar to mega stones, there are many of them can be find.
Some rare crystals can even change the form of pokemons, it's the reason why ash-greninja transformed.
(note: I saw other leaks said ash-greninja is in, but the source here didnt mention that)
5th paragraph: Basically, you can ride all(yes, 所有 means "ALL", it does mention "Basically" though) pokemons in the new riding system.
6th paragraph: There are many terrain on the map, that are known as "area" haven't been marked.
Some strong pokemons in the area called as overlord (it's the totem pokemon in the trailer I guess)
7th paragraph: Some new pokemon info, there's a fire + poison type lizard, the rock puppy will evolve to werewolf
(IT DOES NO'T SAY MORE THAN ONE EVO FOR ROCKRUFF)
and a new mushroom pokemon, a snowman pokemon, rugby monkey(or football monkey), a sea cucumber pokemon, a dolphin pokemon.
Final evo for three starters are bow assassin(pretty sure 刺客 translate to assassin), wrestler, siren(100% sure 海妖賽壬 means siren, not mermaid)
8th paragraph: marshadow that leaked by trademark is a new mystical pokemon, it has very special types
