The Steam Deck uses the capacitive thumb stick sensors to completely disable the trackpads as soon as the stick above the respective pad is touched. This works very well, so I think they‘ll implement the same thing here.

I’m just glad they have dual thumbsticks now. I bought their last model on sale but quickly shelved it. Couldn’t get used to the touchpads and didn’t want to spend the next 2 months sucking at every game I played.
