hi everyone, I'm close to two people involved with PLA QA, they have told me a bunch of stuff from memory so a few things might be a bit off.

The starter evolutions do NOT have Hisuian forms, they are the same

Arceus is not catchable at the end but can be rebattled and it's level gets higher every time

The game ends with a teaser about a new Legends game, where the trainer hears about another region to explore (region not confirmed, either Unova or Kanto)

The events you unlock by having save date of old games give you a special pokeball that's similar to a master ball, looks like apricorn ball but purple)

Hisuian Arcanine looks like Growlithe's new design just bigger, the design is really underwhelming

There will be a new evolution of Voltorb

One of the new Noble pokemon is not an evolution, its completely new and is the Pikachu clone of this game (like pachurisu and dedenne)

will be back with more info soon.
