Last Thursday, Nintendo finally revealed the long-awaited successor to the Nintendo Switch the Nintendo Switch 2 following months of leaks and fervent rumors. As you can imagine, theres been a lot of speculation about Nintendos upcoming console, from hardware specs and pricing to suspected launch titles and comparisons to Valves Steam Deck. One question in particular has pundits and Nintendo fans especially perplexed: What the heck is up with that so-called C button on the Switch 2 Joy-Cons?We likely wont have any hard answers to any of these questions until the Switch 2-focused Nintendo Direct scheduled for April. But that doesnt mean we cant speculate! We put our heads together and came up with a list of what we think the button is for and what we hope the button is for. There are no wrong answers er, or at least not until we get real answers in April so feel free to chime in in the comments on what you think the C button will do!ChatThis one is probably the most probable of the theories out there. As Polygon editor-in-chief Christopher Plante previously speculated, the C button is rumored to open an in-game text or video chat system that allows Nintendo Switch 2 owners to communicate freely with one another and make the process of joining multiplayer games easier. It would be a welcome improvement on the original Switch, as well as offering the opportunity for a playful new UI experience.ColumboEvery once in a while, we could all use some help. Who better to offer that helping hand and a word of advice than Lieutenant Columbo, the shrewd and zen-like detective immortalized through the late, great Peter Falk? If you press the Columbo button, youll be treated to one of the detectives wry catchphrases and witty bon mots. If that doesnt sound like a quality-of-life feature, I dont know what does.AI assistantFor those asking, the new C button is used exclusively to access Nintendo Switch 2's exclusive AI assistant feature Paul Watson (@ghostlycola.com) 2025-01-16T14:51:45.544ZNowadays, it feels like everything and anything has an obligatory AI assistant. Your phone, your car, your blender you name it. So why shouldnt the Nintendo Switch 2 (other than that nobody asked for it)? Pressing the C button could possibly conjure up an AI assistant avatar modeled after one of Nintendos many iconic characters, offering helping in-game tips or shouting a catchphrase.Screen capture/screen sharing (click)A lot has changed in the world of gaming since the Nintendo Switch launched in 2017. One thing that could definitely do with a change is the way players share screenshots and videos of their favorite gaming moments with one another. Thats where the Switch 2s C button could come in. One of our leading theories is that the button could, in addition to a proprietary chat function, allow players to snap pictures or stream videos of their favorite in-game moments or interactions. What would this function be called? Why, click, of course!Coin noiseWho doesnt love the sound of collecting a coin in Super Mario Bros.? Dont you wish you had a button dedicated to delivering the sweet dopamine rush of that dulcet tone in whatever game youre playing, Mario or not? Well, thats what the C button might be for! Just keep pressing it to your hearts delight, whenever the occasion calls for it! Beat a really challenging boss? P-yoing! Got a super hard achievement? P-yoing! Feeling down?
