I'm posting some info about upcoming Sun and Moon games. You decide, if you want to believe. Some things may be intentionally fake.

- Lycanroc forms aren't really version exclusive. You can evolve your Rockruff in the opposite form in the post-game.
- Fighting Abra line IS a thing and there's really cool backstory behind it.
- Some trainers in the game MAY USE non-Alolan forms of certain Pokemon.
- Think of Ultra Beasts and certain Aether Foundation characters as Hulk/Bruce Banner situation.
- Ultra Beasts are looking for a new place to inhabit after their original home was destroyed.
- A certain weapon in a certain war MAY have something to do with this.
- What Zinnia said in Episode Delta has a huge foreshadowing for S/M
- Huge theme of the game is tradition vs progress. Neither is shown as only good or only bad.
- Guzma became an outcast after Tapu Koko didn't accepted him as a Captain. He may be an antagonist at first, but he became sort of a scapegoat for Alolan people.
- Aether Foundation are manipulating Team Skull in order to give people an enemy and a reason for their sanctuary. Ironically they are being manipulated by the true villain.
- The true villain of S/M is REALLY evil. Ghetsis type. Kinda good of hiding it, though. Think some of the better villains in Ace Attorney series.
- Tapu have unique mechanic when you have more than one. Think about them not as legendaries, more like Lucario/Zoroark niche.
- Passimian has an evolution (Fighting/Ground) while Oranguru has a pre-evolution.
- They toyed with the idea of the game scaling and being non-linear at some point in the development
- Speaking of which - starters DO have split evos based on night/day system. They were added pretty late to the game due to the leak of the forms we've seen.
- Confirmed, all Megas can now hold items.
- Z forms are a thing, their appearance (color scheme, some of the markings) will be based on your trainers clothes. Nothing major.
- There is one Z form for each type.
