MobaPad is a Switch controller and game case maker (that I have never heard of), so they should have reliable info. They said that:
- The Switch 2 will have physical cartridges and the slot will also be able to accept Switch 1 games.
- There will be a new button on the back of each Joy-Con, behind the triggers.
- There will be a new button on the right Joy-Con, by the Home button.
I’d only sell my switch to go to a switch 2 when the switch 2 is hackable.
