Probably:
- More about Iwanko and Nekkoala, including their official English names!
- Revealing a couple of new Pokémon.
- More info about Hau.
Maybe:
- A little closer view of what will be the 2nd island we visit.
- One Gym Leader.
- A little more info about Lillie.
- More Mega Evos?
- A new event (apart from that of Magearna)...
- More info about Alola, maybe even a bit of its history!
- If any evo, maybe the 1st evo of the Starters...!
Hopefully:
- The
absolute confirmation of whether or not there
will be character customization. We all hope for it. We can see the character in different clothes in the trailers, but will it really be in the game?
Let's really hope so!
- Hint of a 3rd Legendary...?
