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

• The rumored Nintendo Switch 2 "C" button may facilitate chat functionality.
• Datamining suggests a group and voice chat feature, codenamed "Campus," for the Switch 2.
• The official Switch 2 reveal is expected on January 16th.

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

Since late 2024, numerous Switch 2 leaks have emerged, likely due to the console entering mass production. Consistent across these leaks is an extra button—a dark gray "C"—located on the right Joy-Con, below the home button. However, its function remained unknown until now.

Datamining of the latest Switch OS reveals a feature codenamed "Campus," potentially related to group and voice chat for Nintendo Switch Online subscribers. This information originates from a rapidly growing Switch 2 Discord server.

Nintendo Switch 2: Screen Sharing Capabilities

The same source points to Campus enabling screen sharing for up to 12 users within chat groups. While the codename starts with "C," the button's function is more likely "chat," rather than directly referencing "Campus." This refutes the popular theory that the "C" button would be for screen casting.

Chat Functionality and the Switch's Family-Friendly Image

Group and voice chats necessitate internet connectivity, likely restricting them to NSO subscribers on the Switch 2. This is a significant consideration, given Nintendo's previous design choices. The original Switch's lack of chat features contributed to its kid-friendly appeal. Reintroducing this functionality could introduce potential issues Nintendo may wish to avoid.

The existence and purpose of the "C" button should become clear soon. Multiple sources anticipate the official Switch 2 announcement this Thursday, January 16th.
