Rumors surrounding the Nintendo Switch 2 continue to build momentum, with fresh insights suggesting the mysterious new “C button” may serve a very specific—and social—purpose. According to recent datamining findings, this as-yet-unconfirmed button, reportedly located on the right Joy-Con just below the home button, could be directly tied to chat functionality within Nintendo’s upcoming console.
What the C Button Might Actually Do
Dataminers have uncovered references in the latest Switch OS firmware pointing to a feature internally code-named Campus. While the name starts with a “C,” it's more likely that the button itself stands for “Chat”—not “Campus.” This feature is said to introduce group and voice chat support exclusively for Nintendo Switch Online (NSO) subscribers, marking a notable shift in Nintendo’s traditionally kid-friendly design philosophy.
If true, this would represent a major evolution in how players interact on the platform. The Campus feature is also rumored to support screen sharing and allow chat groups of up to 12 users—an impressive upgrade from anything Nintendo has offered before. This development could potentially render outdated the popular theory that the C button was meant for casting gameplay to other devices.
Nintendo Switch 2: Official Reveal Expected Soon
With the console reportedly entering mass production in late 2024, leaks have become increasingly consistent—especially regarding hardware changes like the addition of the C button. While earlier leaks showed its physical placement, they offered no clues about its function. Now, thanks to ongoing analysis from a rapidly growing Discord community focused on Switch 2 developments, we may finally be getting closer to understanding its purpose.
Why This Matters for Nintendo Fans
Introducing voice and group chat represents a bold move for Nintendo, a company long known for prioritizing child safety over online interactivity. Unlike the open communication channels found on competing platforms, the original Switch avoided built-in chat systems—largely to keep the experience family-friendly. If Campus rolls out exclusively through NSO with moderation safeguards, it could strike a balance between modern multiplayer expectations and Nintendo’s protective stance.
All eyes are now on January 16, when multiple credible sources indicate the Nintendo Switch 2 will be officially revealed. Until then, the C button remains one of the most talked-about hardware mysteries—and these latest findings make a strong case that it’s all about connection, not casting.
