Updated on January 14: The original version of this article linked to a different Discord server, also called "Nintendo Switch 2." The link has been changed to reflect the real source of the datamining effort. The original story is as follows.
Summary
- The Nintendo Switch 2's rumored C button may be used for chat functionality.
- Recent datamining efforts suggest the Switch 2 will support a group and voice chat feature code-named Campus.
- The next Nintendo console will reportedly be officially revealed on January 16.
Rumors about the Nintendo Switch 2 have been swirling, and the latest buzz centers on the mysterious C button rumored to be a new addition to the console's design. According to a recent report, this button might be linked to enhanced chat functionality, offering a peek into what we can expect from Nintendo's next gaming marvel.
Since late 2024, leaks about the Nintendo Switch 2 have been rampant, fueled by the console reportedly entering mass production. These leaks consistently showed an extra button labeled with a dark gray "C" on the right Joy-Con, just below the home button. Yet, until now, no one had a clear idea of what this button was meant to do.
Thanks to diligent datamining efforts within a burgeoning Discord server focused on the Switch 2, we now have a clue. The latest version of the Switch OS reportedly contains references to a feature called "Campus," which seems to be related to group and voice chat support for Nintendo Switch Online subscribers.
Nintendo Switch 2 Will Reportedly Support Screen Sharing

The same source hints that Campus will enable screen sharing and allow chat groups to include up to 12 users. Given its codename starts with a "C," it's tempting to connect this feature to the new C button. If true, this button might stand for "chat" rather than "Campus," debunking theories that it's meant for casting the console's screen to other devices.
Chat Support Isn't Exactly in Line With the Switch's Kid-Friendly Design
Introducing group and voice chats would require an internet connection, and if implemented, it might be exclusive to Nintendo Switch Online subscribers. This move seems at odds with the original Switch's design, which avoided such features to maintain a family-friendly atmosphere. Adding chat functionality could complicate Nintendo's efforts to keep things safe and simple for younger gamers.
The true purpose of the C button on the Nintendo Switch 2 might be revealed soon. Multiple sources indicate that the much-anticipated console will be officially announced on Thursday, January 16.
