Hey there. After we got our rugby monkey today, I decided to go back and look at the original transcript for the Chinese leak. All the stuff we've known had been shortened for succinctness so I thought maybe we could have missed something. Being a fluent speaker of Mandarin, I went back and translated the conversation word for word. Here it is to anyone who wants to read it. There really isn't anything too new, but there are some aspects that the previous translator didn't address. The bold is the translation and I added some stuff in non-bold.
"Everyone knows that this time, the Chinese dialogue (translation) had participation from Chinese people. The "uncles" on the inside (an affectionate way to refer to localizers, translators, etc...you will get it if you understand the culture. We refer to people older than us as either uncles, aunts, older brothers/ sisters, grandpa, grandma, etc...even if we aren't related) weren't careful and even though information leaks have been mostly contained, a lot of information has actually been leaked to a greater extent. Here is some info, but I can't guarantee legitimacy.
As it has been circulating priorly, there are no gyms in Sun and Moon. This is because the main story involves the creation of a new league. Alola has no league so naturally there are no gym leaders. The plot involves the professor requesting the main character to make a league. In replacement of gym leaders, there are training masters called captains. The replacement for the four heavenly kings (E4) are the island kings (Kahunas) of each island. After the formation of the league, there will be four heavenly kings.
The new bracelet can power up all skills. You can put the diamond stones seen on the game logos onto it. There are a lot of different kinds and they need to be collected very much like mega stones. Some of the diamond stones can even change the form of pokemon. Xiao Zhi frog (Ash-greninja) relies on this device to change form.
The new riding system basically allows you to ride all pokemon. There are unmarked areas on the map known as districts. Within these districts are very powerful pokemon called overlords (or tyrants).
In regards to new pokemon, there is a fire + poison type lizard, stone puppy (rockruff's Chinese name translation) will evolve into a werewolf. (The character used here indicates that rockruff "can" evolve into a werewolf, not that it "has to") There is a new mushroom pokemon, snowman pokemon, olive ball (Chinese for American football or rugby) monkey, sea cucumber pokemon, dolphin pokemon. The three starter's final forms are an archer, wrestler and siren.
The previously trademarked marshadow is a new mythical beast (legendary pokemon). Its typing is very unique.
At the moment, I only know of this information."
