A good friend of mine is close with some people involved with the making of Pokemon Sun and Moon. You can ask me anything about the game, and I will do my best to answer.
To start:
- The Chinese Leaks are real.
- Megas are returning, and there are new ones for some Pokemon:
- Cinccino (Normal/Fairy)
- Garbodor (Poison/Water)
- Palkia (Water/Dragon)
- Dialga (Steel/Dragon)
- Reshiram (Dragon/Light)
- Zekrom (Dragon/Dark)

- There are more Aloha forms, but only for gen 1, as predicted:
- Arcanine (Water)
- Kabutops (Bug/Water)
- Omastar (Water)
- Darkrai (Light)
- Cresselia (Psychic/Dark
- Conkeldurr (Psychic)
- Popplio (Ice/Fighting)
- Mudbray (Flying/Fairy)

- Team Skull is not the real evil team
- Real evil team is Team Doom
- Lillie works for Team Doom
- 4 Kahunas per island
- Middle island is the elite four, which you make by assigning Kahunas
- 2 postgames
- Go back to Sinnoh and stop team doom from taking giratina
- Another episode with Zinnia but part 2

Feel free to ask questions.
