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 may facilitate chat functions.
• Datamining of the latest Switch OS reveals a feature codenamed "Campus," hinting at group and voice chat capabilities.
• The official Nintendo Switch 2 reveal is expected on January 16th.

Recent reports indicate the Nintendo Switch 2's rumored "C" button might be dedicated to chat functionality. This could resolve a significant question surrounding the new console's hardware.

Leaks regarding the Switch 2 have proliferated since late 2024, likely due 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 a mystery until now.

Datamining of the latest Switch OS, reported from a prominent Discord server focused on the Switch 2, unearthed a feature codenamed "Campus." This appears to be a group and voice chat system for Nintendo Switch Online subscribers.

Nintendo Switch 2: Screen Sharing Capabilities

The same source suggests "Campus" will include screen sharing and support groups of up to 12 users. While the codename begins with "C," the button's function is more likely related to "chat" than "Campus" itself. This discovery counters the popular theory that the "C" button would be used for screen casting.

Chat Functionality and Nintendo's Family-Friendly Approach

Group and voice chats necessitate internet connectivity, likely limiting access to Nintendo Switch Online subscribers. This is a significant consideration, given the Switch's deliberate move away from such features. The omission of chat functions contributed to the Switch's family-friendly design. Reintroducing this functionality, similar to the Miiverse text chat, could present challenges Nintendo might prefer to avoid.

The existence and purpose of the "C" button, along with other Switch 2 features, should be clarified soon. Multiple sources anticipate the official announcement of the Switch 2 on Thursday, January 16th.
