Nintendo fans are buzzing with excitement following the discovery of new filings that hint at the possibility of a new GameCube controller designed for use with the upcoming Nintendo Switch 2. The controller, believed to be wireless and compatible with Bluetooth technology, could potentially be used to play GameCube classics through the Nintendo Switch Online subscription service.

As reported by Nintendo Life, the recent FCC filing for a "game controller" aligns with the Switch 2's specifications, sparking speculation that this could be a new iteration of the beloved GameCube controller. The internet sleuths at Famiboards delved into the filing and noticed that one of the images shows a label location that matches the positioning on the back of a GameCube controller, specifically behind the C-Stick.

While some speculate that this could be a new version of the Switch Pro Controller, the prevailing theory suggests its primary use will be with the Nintendo Switch Online service, which already supports wireless classic controllers for retro gaming. This development has reignited hopes among fans for a GameCube library to be added to the service, which currently offers games from the NES, SNES, N64, Sega Genesis, and Game Boy.

The Nintendo Switch 2 was unveiled earlier in January with a trailer that confirmed its backwards compatibility and the addition of a second USB-C port. However, many details, including the function of a mysterious new Joy-Con button and other game titles, remain undisclosed. The Joy-Con mouse theory has gained some traction, suggesting innovative control options.

Last month, a Nintendo patent hinted that the Switch 2's Joy-Con controllers could be attached upside down, utilizing magnets instead of the original's rails. This design change could allow players to customize the placement of buttons and ports, potentially leading to new gameplay mechanics.

Analysts predict that the Switch 2 will be priced between $400 and $500, with a possible release in June. Nintendo has scheduled a Direct for April 2, where more details about the console are expected to be revealed.

In the meantime, fans can enjoy a taste of GameCube nostalgia with Metroid Prime Remastered, available on the current Nintendo Switch.
