I'm wondering if the anticipated Switch 2 is going to be very similar to the current device in terms of architecture and OS, and the real concern of Nintendo isn't Switch 1 piracy right now, it's that the current Switch emulators could evolve into Switch 2 emulators in the early months/years of the new hardware lifecycle, emulators able to play ripped Switch 2 games well before anyone figures out how to mod the new hardware to enable piracy.
But they probably also want to re-sell us previous games, too, particularly if they can run 'remastered' versions of the Switch Zelda games at a better resolution/framerate on the new hardware - which you can already to via emulation...
