Every now and then a patent or trademark filed by a company in the video game industry will stir up conversation, and one currently has a lot of people talking. On December 5th, Nintendo filed a trademark for the image of the Super Famicom controller. It's classified under the category for video games, but no additional details have been provided.
Many are speculating that it's a hint that an SNES Classic Edition console is on the way, but it's also entirely possible that Nintendo is covering their bases. After all, they've been especially protective of their IP in recent months.
