My bet is that in BDSP we’ll have plenty of ”Legends say that this crater was caused by battling Legendary Pokemon hundreds of years ago!”But this is like them going “here’s HGSS... and next year, an open world Johto game!”. They never really do a region twice in a row. And Kanto being in GS after RBY is different due to the sequel nature of those games.
Unless the 2022 game is a sequel to the 2021 game?
