Czech online store SuperGamer has revealed that "Metroid Prime 4" for the Nintendo Switch is scheduled to be released on "November 29, 2019."
Considering two core "Pokemon" titles is rumored for a November 2019 release on the Switch; a November release for Metroid Prime 4 conflicts with Nintendo's historical business strategy.

In 2017, Super Mario Odyssey took the spotlight on Black Friday; followed by Xenoblade Chronicles 2 in December.
In 2018, Pokémon: Let's Go, Eevee! and Pokémon: Let's Go, Pikachu! took the spotlight on Black Friday; followed by Super Smash Bros. Ultimate in December.
