There is already proof that it can be hacked; "Mig-Flash" style devices work on the Switch 2—we can create a card similar to the old DS R4 cards. Thanks to the "game card key" system, we can make this work without needing exact 1:1 copies of genuine cards (like the Sky3DS did). We can load game data onto the flash card—let's call it "Switch2Flash"—along with either a fake or a real activation key. Initially, the card could be used to install games offline or even run them directly if possible. We’ll also be able to spoof keys for fully digital games to play them, and even put DLC and update on the card, since the game key itself is enough to play.
Game card keys make it possible to create R4-style solutions for any game. If the Switch 2 doesn't end up with something like Atmosphere, creating fake physical cards with activation keys offers an advantage to R4 creators: they can combine physical data with keys to force the use of Switch 2 games.
At least it remains a possibility.
Sorry about my English; I'm using Google Translate, so I don't know if I'm making myself understood.
