Nintendo’s suit lays out what it calls a “timeline of Genki’s wrongdoing,” which began in December 2024 when the company publiclytweetedin response to GameStop CEO Ryan Cohen to discuss “the launch switch 2 accessories [Genki was] working on.”

Genki’s most famous Switch 2-related incident came in January 2025, when an exhibition page for Genki’s presence at the Computer Electronics Show 2025 was posted. The page read, “Happy to discuss any Switch 2 info we may have as well as the stuff we’re making for it.”

Shortly after this, Genki CEO Edawrd Tsai“personally showed off the 3D-printed mockupsand stated to different reporters that Genki had or had access to an authentic “Switch 2,” on which Genki based the mockups, renderings, and 3D-printed mockups,” according to the suit.

Nintendo goes on to allege that multiple company representatives, including Tsia, also “did multiple media interviews discussing their eight accessories” and purportedly confirmed specific, highly confidential designs and functionality of the not-yet-announced Nintendo Switch 2.
