Nintendo filed four separate applications with the European Union Intellectual Property Office. They were each for controllers for the N64, NES, SNES and Nintendo Switch. It’s entirely possible that Nintendo might be making unique controllers for the Nintendo Switch’s eventual Virtual Console.
However, Rösti posits that the “goods and services” nature of the filings indicates that we’ll see the Classic Edition for the Nintendo 64.
Whatever it is, let’s hope Nintendo makes more than six of them this time around.
