Pokemon Z is going to be the next titles in the series, and SwSh takes place in the original universe and so will Z.

>The Darkest Day happened the same exact time AZ fired the Ultimate Weapon
>A swimmer states you can swim from Galar to Kalos, meaning they're close together
>The Kalos Elite Four shilled SwSh in the mobile gacha Pokemon Masters
>The Gen 7 starters and legendaries are in SwSh but nothing for Gen 4 (Remakes after Z) or 6, despite Gen 6 being on the 3DS
>Mega Blaziken was in XY and hinted at a Gen 3 remake as well as Swampert and Sceptile also getting Megas, and since Gigantamax replaces Mega Evolution in this universe, Charizard hints that Blastoise and Venusaur will get Gigantamax forms in Z when Professor Sycamore gifts you one at his lab
>Zygarde had a purpose in Alola instead of Kalos (Anime doesn't count)
>Sonia constantly states Zacian and Zamazenta are from a different region
>Zacian and Zamazenta start with the letter Z

It will be a remake of XY in the original universe with the wild area from SwSh copy pasted as the postgame
POKEMON Z IS FINALLY HAPPENING
