New Nintendo regulatory filings have sparked excitement among fans about a potential GameCube controller revival, possibly designed for playing GameCube classics through Nintendo Switch Online on the upcoming Switch 2 console.

As reported by Nintendo Life, Nintendo's recent FCC submission for a Bluetooth "game controller" aligns with the Switch 2's development. Internet investigators (Famiboards) analyzed the documents and noted that one image shows label placement identical to the rear positioning on original GameCube controllers - specifically behind the C-stick.

While this could simply be a new Switch 2 Pro Controller, speculation suggests it may connect to Nintendo's Switch Online service, which already offers wireless classic controllers for retro gaming.

The discovery has reignited hopes for GameCube games joining Nintendo's subscription service. Fans have long requested GameCube classics on Switch, though Nintendo has currently limited its retro offerings to NES, SNES, N64, Sega Genesis and Game Boy titles. Could the Switch 2 finally deliver this highly-anticipated catalog?

Nintendo unveiled the Switch 2 in January with a teaser confirming backward compatibility and an additional USB-C port. While details remain scarce, the brief reveal fueled theories about Joy-Con functionality, including speculation about gyroscopic mouse-like controls.

A recent Nintendo patent revealed potential upside-down Joy-Con attachment capabilities for Switch 2. Unlike the original Switch's locking rail system, magnetic connections would allow more flexible controller positioning - potentially enabling customized button layouts and innovative gameplay applications.
