Is Nintendo working on a new game system, if Nintendo Switch is axed in 2025

As of my last knowledge update in October 2023, there had been no official announcement from Nintendo regarding a new gaming system to replace the Nintendo Switch after 2025. However, it's common for companies in the gaming industry to work on new hardware well in advance of a release. Given the Switch's success, speculation about what might come next is prevalent among fans and analysts. For the most current information, including any announcements about new hardware, I recommend checking Nintendo's official communications or reputable gaming news sources.
