>>40003557Almost every gen has gotten a newer release: Be it as a sequel or a third version, seeing how much money they made off USUM means they'll probably make this the norm because of course: Why just release a third version when you can make just an enhanced double version and get twice the revenue?
Remember that Gamefreak aren't stupid, they're just opportunistic assholes. Given how much controversy the lack of National Dex has sparked it wouldn't be a surprise if they used it as the main selling point for the re-releases as well as brand-new Gigantamax forms
So in conclusion: You can expect Pokémon MAX Sword and MAX Shield to happen by late 2020, most likely in November too
