Here is something interesting. Nintendo filed trademarks for four different controllers in Europe on July 18. Among these were the NES, SNES, and Switch controllers. However, in addition to these, they also filed one for the N64 controller.
What is important to note was that each filing was registered under the same goods and services category. This is connected to physical products rather than digital, which has led to speculation that an N64 mini is coming. We need to wait and see, but what games would you want on it?
