Four hidden design registrations in Europe hint that Nintendo could be working on a brand-new Switch 2 accessory, but nobody knows exactly what it is yet.
Nintendo has a habit of surprising players with ideas nobody sees coming. One day it's cardboard toys that transform into game controllers, another day it's a smart alarm clock filled with Mario and Splatoon characters. Now, the company has sparked fresh curiosity after quietly filing a new set of design registrations that could point to its next hardware project.
Nintendo recently submitted four design registrations to the European Union Intellectual Property Office (EUIPO). While that might sound routine, there's an interesting twist. The company has chosen to delay publishing the designs, meaning the public can't see what the product actually looks like just yet.
The four filings all share the same design number prefix, suggesting they're tied to a single product rather than several different ones. That has naturally led fans to believe Nintendo is preparing one new piece of hardware with multiple design variations or components.
Nintendo has used this strategy before.
One of the earliest filings for the Nintendo Switch Online Nintendo 64 controller revealed almost nothing. The design shown publicly was little more than a plain shape that existed only to meet legal requirements. Once the publication period ended, the full controller design was finally revealed.

That history is why many fans think these latest filings could be hiding another surprise.
But what exactly could Nintendo be working on? Right now, most signs point toward an accessory rather than an entirely new console. Nintendo has never been afraid to experiment with unusual hardware, whether it's the Ring Fit Adventure exercise ring, Nintendo Labo, or more recently Alarmo. Those products weren't expected, but they fit Nintendo's reputation for trying something different.
One possibility is a brand-new controller designed for a specific game or gameplay style. Another theory is an official accessory built around the Switch 2's mouse mode. Although third-party companies already make mouse grips and similar add-ons, Nintendo hasn't released its own first-party version despite putting more attention on the feature. Then there's another idea that's getting plenty of attention among fans.
Could Nintendo be preparing for Nintendo DS games on Switch Online? Some believe the mystery accessory could make it easier to play dual-screen DS titles on modern hardware. One suggestion is a vertical grip that lets players hold the Switch 2 in portrait mode, stacking two virtual screens on top of each other to recreate the original DS layout.
It could even include a place to store a stylus, making touch-based games feel much more natural.
Of course, none of these theories have been confirmed. Nintendo hasn't officially announced a new accessory, and the hidden filings reveal almost nothing beyond the fact that something is being prepared behind the scenes. Still, if history has taught fans anything, it's that Nintendo rarely follows the expected path.
The company's biggest surprises sometimes come with very little warning, and these fresh patent filings have just added to the intrigue. For now, all eyes are on Nintendo as everyone waits for those hidden designs to become public. The only real question is whether the company is about to reveal another clever accessory—or something nobody has even thought of yet.
