A patent from Nintendo suggests that they're working on a magnetic joystick system, aka hall effect joysticks, which would solve stick drift.
A patent filed by Nintendo suggests that they’re working on Hall Effect style joysticks for the Switch 2 that would eliminate stick drift almost entirely.
It’s a way to detect which way the stick is pointing using magnets. It’s way more accurate and incredibly reliable.
Also because the moving parts don’t actually make contact with the sensors, the wear issues that affect joycons basically don’t exist
