Nintendo has officially confirmed that the mysterious new button on the Nintendo Switch 2's Joy-Con is indeed the C button, putting an end to the swirling rumors. This confirmation came via the newly announced and released Nintendo Today! app, whose listings on the App Store and Google Play include an image that, upon close inspection, clearly displays the letter C on the button.
The new C button was first revealed alongside the Switch 2 earlier this year, though initial images of the Joy-Con did not feature any lettering on the button. Previous reports had speculated it was the "C" button, and those reports have now been validated.

Speculation abounds regarding the function of this new button. Some theories suggest it might be used for wirelessly casting the Switch 2 to a TV or for screen sharing. Others speculate it could switch the Joy-Con into a mode that functions like a mouse. There's also talk that it might be related to new group or voice chat features.
Nintendo has scheduled a Switch 2 Direct for April 2, where we hope to learn more about the C button and other features. In the meantime, here's what we know for certain:The Nintendo Switch 2 is set to launch in 2025, likely not before June, based on the hands-on event schedule. It's larger than the original Switch, with bigger Joy-Con that appear to be usable as a mouse. The Switch 2 features two USB-C ports, one at the top and one at the bottom, unlike the original Switch which had only one. The console is backward compatible, capable of playing both physical and digital Nintendo Switch games as well as Switch 2 exclusives, though some Switch games may not be fully supported. A new Mario Kart game is also in development for the Nintendo Switch 2.
