With the Nintendo Switch 2 Direct just hours away, excitement builds for Nintendo’s next console unveiling. A recent Federal Communications Commission (FCC) filing may offer clues about the upcoming Switch 2 controller lineup.

Discovered on Famiboards and reported by Nintendo-focused outlets like GoNintendo, an FCC filing surfaced on March 31 from Nintendo. Listed under product code "BEE-008," it appears to register a new game controller, with some enthusiasts speculating it could be the Nintendo Switch 2 Pro Controller.

It’s worth noting that this remains unconfirmed, as Nintendo has not officially announced a Switch 2 Pro Controller. However, features like Bluetooth and NFC support suggest it could align with a Pro Controller design.

A key detail in the filing, if it pertains to the Switch 2 Pro Controller, is the potential inclusion of a headphone jack. Unlike the original Switch 1 Pro Controller, which lacked this feature, modern controllers like the DualSense and Xbox Series include such a port.

Adding a headphone jack would enhance user experience, if confirmed for the Switch 2 Pro Controller. Previous Nintendo FCC filings have often hinted at future plans, lending some credibility to this speculation. Without further leaks, clarity will likely come during Nintendo’s official Switch 2 reveal tomorrow.

The Switch 2 Direct is set for tomorrow at 6am PT / 9am ET on Nintendo’s channels, promising a "closer look" at the console following its initial tease earlier this year. Fans anticipate detailed insights, possibly including a release date.

Nintendo has stated the Switch 2 Direct will last one hour. Additionally, two Nintendo Treehouse: Live | Nintendo Switch 2 events featuring hands-on gameplay are scheduled for April 3 and April 4, starting at 7am PT each day.
