It's the day before the highly anticipated Nintendo Switch 2 Direct, and excitement is building as we're just hours away from learning more about Nintendo's next big console. A recent Federal Communications Commission (FCC) filing has sparked speculation about what could be part of the Switch 2's controller lineup.

As reported on Famiboards and echoed by Nintendo-focused sites like GoNintendo, an intriguing FCC filing surfaced on March 31 from Nintendo. Listed under the product code "BEE-008," this appears to be a registration for a new game controller. Many fans are speculating that this might be the Nintendo Switch 2 Pro Controller.

It's important to note that this is still speculation, as Nintendo has not officially confirmed the existence of a Switch 2 Pro Controller. However, some details from the filing suggest it could indeed be a Pro Controller, featuring Bluetooth and NFC capabilities.

While past Nintendo filings have occasionally foreshadowed the company's plans, we should take this information with a grain of salt until officially confirmed. Without further leaks, we'll likely get the full picture during tomorrow's Switch 2 Direct.

The Switch 2 Direct is set to stream tomorrow at 6am PT / 9am ET across Nintendo's channels. Fans are eagerly awaiting a "closer look" at the Switch 2, following its initial reveal earlier this year, with hopes of getting solid details on features and a potential release date.

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