Updated January 14: This article's original Discord server link has been corrected to reflect the accurate source of the datamining information. The original article follows:

Key Findings

• Rumors suggest the Nintendo Switch 2's additional "C" button facilitates chat functions.
• Datamining of the latest Switch OS reveals a feature codenamed "Campus," hinting at group and voice chat capabilities for Nintendo Switch Online users.
• The official Nintendo Switch 2 reveal is expected on January 16th.

Recent reports suggest the Nintendo Switch 2's rumored "C" button may be dedicated to chat functionality. This revelation could significantly clarify a key mystery surrounding the upcoming console's hardware.

Since late 2024, numerous leaks have surfaced regarding the Switch 2, largely attributed to the console entering mass production. These leaks consistently show an extra button—a dark gray "C"—on the right Joy-Con, below the home button. However, the button's function remained unknown until now.

Datamining the latest Switch OS update, a fast-growing Discord community dedicated to the Switch 2 uncovered a feature codenamed "Campus." This feature appears to be a group and voice chat system for Nintendo Switch Online subscribers.

Nintendo Switch 2: Screen Sharing Capabilities

The same source indicates "Campus" will enable screen sharing among up to 12 users. While the codename begins with "C," the button's function is more likely "chat," rather than a direct correlation to "Campus." This contradicts earlier speculation that the "C" button would be used for screen casting.

Potential Conflict with the Switch's Family-Friendly Focus

Group and voice chats require internet connectivity, likely restricting their use to Nintendo Switch Online subscribers. This raises concerns, given the Switch's deliberate move away from such features to maintain a family-friendly environment. Reintroducing features like text chat could introduce issues Nintendo may wish to avoid.

The existence and purpose of the "C" button, along with other Switch 2 details, should be clarified soon. Multiple sources point to an official announcement this Thursday, January 16th.
