This is my first time posting on 4chan but I thought the information was worth sharing. You might not believe me but I know these leaks are real.

1. There are two professors who ara siblings yet are separated because of their different ideals. Only one of them gives you a pokemon the other one gives you the Pokédex.
2. Even though you started from the bottom of the map most of it is explorable after the elite 4.
3. Speaking of the elite four they help you throughout the story and play a major role in reuniting the Galar region.
4. There are two Evil teams namely house sword and house shield. The members of these two groups are knights belonging to their respective clans/houses. House sword specializes in brute force while house shield is the expert of stealth.
5. Evil teams are not version exclusives except for the boss battles.
6. There is no order of the gyms, at least for the first 6 gyms. Each gym master is either a member of house sword or house shield. The last two gym masters are the leaders of the two houses and the order depends on the version you pick.
7. You have to complete special requirements before challenging the gym masters. There are mini side quest after each gym.
8. Your rival is the protagonist of the other gender and is unfortunately very friendly. However he/she is very competitive and keeps maturing as the story progresses.
9. Grookey evolves into a Grass/Psychic type chimpanzee like Pokémon.
10. Scorbunny evolves into a Fire/Fairy type Pokémon and represents sportsmanship.
11. Sobble evolves into a Water/Ice type Pokémon sharing resemblance to the Loch Ness monster.
12. There are two new eeveelutions being Steel and Dragon types.
13. Looks like there are 87 new Pokémon excluding Meltan Melmetal and regional variants.
14. The first boxart legendary is a giant serpent from Norse mythology and is a Steel/Dragon type.
15. The other legendary is an eight-legged Pegasus like Pokémon which is a Steel/Fairy type.
