I wouldn’t be surprised if it’s one of the last big releases on Switch.

We know that the Switch’s successor won’t be out until FY2024, so April 2024 at the earliest. There’s also some indication that Nintendo is going to build a bit of a stockpile before launching to reduce scalping. I think that fall 2024 is the earliest realistic launch window. Even then, it’s possible that Nintendo keeps releasing games for the Switch after the next console launch (as Sony has kept the PS4 going post-PS5).

Nintendo has a packed release schedule through November 2023 and then there’s nothing. The only confirmed games with no release date are Luigi’s Mansion 2, Metroid Prime 4, and the Princess Peach game. It’s possible that those all come out next year for the Switch.
