New Nintendo Trademark Filing Gives Hope For N64 Classic
A trademark application for the N64 controller potentially points to a new micro console.

Nintendo's next micro console, SNES Classic, is set to launch this fall, but that may not be the end of the company's retro plug-and-play line. A new trademark filing suggests that a miniature Nintendo 64 could also be on the way.

The filing in question is for a controller that appears identical to that of the Nintendo 64. Nintendo recently applied for a trademark for the distinctive three-pronged gamepad with the European Union Intellectual Property Office (via NeoGAF). The application is listed under goods and services, which suggests the trademark pertains to a physical product. You can see the image from the filing below.
