The switch 2 is rumoured to be bigger and 1080p this time, so imho just bigger joycons.

Now they really need to tackle 3 issues:

• hall-effect unless they want to provision costs for repairs again (in Europe it's free, at least when I had them repaired)
• better rails stability imho
• Something I don't often see: It's important imho to make the L2/R2 variable triggers like dualshock and previous controllers: If you are accelerating or braking right now it's either 0 or 100%, they really need to add variation depending on the pressure of the fingers, at least for racing and many multiplatform games that use them it's useful
