This is a weird one, but I’d love to see a reimplementation of the sensor bar. The gyro controls haven’t cut it for me. I like how the Wii U game pad had the sensor bar built in to the bezel. The real engineering nightmare would be squeezing IR cameras into the top of the Joycon
please have a headphone jack. idk if this is something we need to actually worry about…but i really dislike that newer phones keep omitting the headphone jack. bluetooth just isn’t the same!
