Been out there for a few days, but Nintendo's European research division (NERD) has put out a job listing, the job alludes to a next-generation Nintendo platform as part of the job as well as cross-generation
https://www.nerd.nintendo.com/files/Job%20Offer%20GAMETECH2023%20EN.pdf
The position focuses more specifically on
• Game engine architecture
• Cross-platform development
• Network programming
• Interactions with large code bases
The goal will be to aim for and go beyond state-of-the-art solutions in these fields, targeting current and next
generation Nintendo platforms.
The operating environments are Windows/Linux, and the Nintendo consoles’ OS and SDK.
So I think that is the first official Nintendo hiring leak we've seen for a next-generation system (inclusive). Nintendo is indeed hiring for positions that will have to work on the new Nintendo next-gen platform, also it mentions cross-platform development so that probably is a tip off that there will be cross-platform Nintendo games for Switch 1 and Switch 2 (to no one's real surprise). Also they refer to Nintendo's console OS and SDK (software development kit) in the plural, so that probably indicates there is a dev kit and OS for the Switch 2, along with just the singular Switch platform.
