It isn’t surprising, but today’s Gamescom Opening Night Live presentation hasn’t had much for Nintendo fans to look forward to. Nintendo isn’t at Gamescom, so first-party games aren’t here. Not only that, but the presentation has had very few third-party and indie games shown that are going to be releasing on the Nintendo Switch.
This is a exception. It has been announced that Little Nightmares 3 is going to be releasing in 2025. The game will be releasing on PlayStation 5, PlayStation 4, Xbox Series X|S, Xbox One, Nintendo Switch, and PC. A new trailer was also shown, so you can see it via Little Nightmare 3’s announcement social media post about the matter down below.

I’m pretty sure that it will be on switch 1 and 2.
I think alot of the games where not announced for switch because they will mostly come to switch 2 which they cannot announce yet.
Nintendo will be announcing all of the games coming to the new console in its own Nintendo direct due to nda’s
