For me I think they should create more ergonomic controllers. The reason I never touch the switch of my son is because of how painful it is to plsy with. The stick are way too low. The dual sense is an amazing controller. Something like the Sony Q looks nice.
I hope they get rid of them. They make the handheld in ergonomic and ruined the amazing wiiu controller scheme they had. I have never had a good time using joycons and they cause too much compromise.
They should keep support so things like ring fit work, but they need to go or not be made for kind of symmetric 2 player.
