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
True, although my gripe is on the principality that they could charge $10 for the replacement parts and still make a nice profit. Even when handling each brand’s controllers with the utmost care, I’ll end up spending $60-$90 in replacement parts for a joycon before I need to replace an Xbox controller, and to add insult to injury, the Xbox controller costs less than a Joycon!
