Theory: Z-A and Zeta Pokémon

What if “Zeta” Pokemon will be this game’s “Alpha” Pokemon?

What if this game IS set within Lumiose City but in a scale not yet revealed? While replaying PLA I was reminded that Pokemon can willingly shrink themselves down in size… what if that’s what will happen?

What if the five parks around the city will feature similar to the Blueberry academy? 5 unique artificial and MINIATURE biomes that with the help of the new group are set up around the city. - perhaps with the help of Zygarde (a cellular Pokemon) we are able to shrink ourselves down tiny and enter these Pokemon havens to discover what is causing a ruckus! - perhaps “Zeta” Pokemon will function like Alphas only being powerful pint sized Pokemon with the title “the former Zeta” - While this would allow Lumiose city to act as a human centric city with Pokemon allowed to follow behind, and partake in the many human/city activities (taking photos, food, tm maker, etc) - While the miniature biomes would be Pokemon and exploration centric
