More regional forms/evolutions, so long as they make sense. I still don't understand Hisuian Sneasel/Sneasler, when Weavile was already a Sinnohan Pokémon. It was a cool design, just would've made more sense on a Pokemon not seen in modern-day Sinnoh.
I have a lot of hopes really, but the reveal was so cryptic it's kinda hard to know what way they'll go, so I'm just excited. More Mega forms, for sure.
More ancestral characters too - damn near all the important characters in PLA were ancestors of existing characters, and those that weren't had great designs, so I'm just excited to see the new characters, overall.
Perhaps more trainer battles. PLA made perfect sense, but it'd be nice to have a few more trainers dotted around the world for battles.
More Pokéball variety would be nice. Specifically, I'd like proper support for old Pokéballs in future games. Their designs are so cool, only to lose them to the "Strange Ball" when transferred.
Lots of hopes, but not gonna torture myself with videos and posts - just gonna be pleasantly surprised once the game drops 😁
