I guess its main games have already released and we shouldn't expect new reveals for it. It feels like the next Mario Party and Metroit Prime 4 are gonna be final exclusive games for it.
Talking about 3rd party, a lot of indie developers will still support the console in 2025 or 2026 but a lot of publishers e.g. Embracer, Electronic Arts or Focus Interactive are likely to stop releasing games on it. While Switch has a big player base, the system's specs are outdated. Therefore there won't be games from some 3rd party companies. The exception is a couple of next Just Dance games and something like that.
