GameRant keeps a running list of every announced Switch game, and archive.org keeps a copy from across history, so we can know exactly what we knew at any position in time.
As of 2nd of April 2021, the following games which Nintendo were involved in publishing had been announced:
New Pokémon Snap, Miitopia, Famicom Detective Club: The Missing Heir, Famicom Detective Club: The Girl Who Stands Behind, DC Super Hero Girls: Teen Power, Mario Golf: Super Rush, The Legend of Zelda: Skyward Sword HD, Splatoon 3, Bayonetta 3, The Legend of Zelda: Tears of the Kingdom, Metroid Prime 4, Shin Megami Tensei V, Pokémon Brilliant Diamond and Shining Pearl, Pokémon Legends Arceus, Triangle Strategy
Out of those, four were released in the first half of 2021, five in the second half of 2021, and the remaining 6 in 2022 or later.
And one of them was announced in early 2021 for a 2022 release, Splatoon 3.
And to supplement that with April 2022:
Nintendo Switch Sports, Mario Strikers: Battle League, Fire Emblem: Three Hopes, Live A Live, Xenoblade Chronicles 3, Bayonetta 3, Mario + Rabbids: Sparks of Hope, Pokemon Scarlet/Violet, Splatoon 3, Advance Wars 1+2 Reboot Camp, The Legend of Zelda: Tears of the Kingdom, Metroid Prime 4.
H1: 4. H2: 5 2023+: 3
Furthest out game with a release window: Zelda, Q2 2023
Here's the equivalent list for 2nd April 2023:
Advance Wars 1 + 2: Re-Boot Camp, The Legend of Zelda: Tears of the Kingdom, Pikmin 4, Metroid Prime 4
Currently we have two games to release in the first half of 2023, one in the second half, and one with a big question mark next to it.
And the "second half" game is for
July, while in previous years it's been September-November.
The Switch is going to break the DS's record for the longest gen since the GameBoy on June 4th of this year. If Nintendo makes it to March of next year without new hardware it will be the longest gap between
revisions of hardware in the 21st century. It's not just weird that Nintendo is going quiet, it's a weird
time to go quiet. If Nintendo intends to keep the Switch around for another year, they need to say so, and then prove it with software releases. But they're saying "uncharted territory" and announcing nothing.
Investors: "Gonna release new hardware"
Nintendo: "You know we're in uncharted territory."
Investors: "People aren't buying evergreens as much anymore. How are you going to reach new customers without new hardware?"
Nintendo: "You need a combination of software and hardware"
Investors: "So what are you going to release for your hardware"
Nintendo: "...games"
Investors: "Like what?"
Nintendo: "Zelda is going to do very well"
Investors: "And after that?"
Nintendo: "Yeah, uncharted territory"
Some Nintendo fans: "Yeah, sounds legit!"
Other Nintendo fans: "It's all part of the new hardware plan Bay Bee!"
