Wait so there will be two different types of cartridges? Some that do hold game data and others that don’t and are just the digital key?

I was under the impression this would be all cartridges for the Switch 2.

They made a change that the cartridges no longer hold the game data but will require a download of the game and the cartridge is just a key for the digital game.

That will stop game dumping from the cartridge. But with a jailbroken console, we can still get the game that way.
