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...
I am sure the Switch 2 is just a more powerful switch. Still massively underpowered compared to a PC so updating the emulators to run switch 2 would be a fast affair considering how easy people were able to dump the first one. Its likely just a "switch pro" iteration that the OLED never was.
Its likely inevitable considering the hunger for pirated nintendo games on markets like Brazil with a large supply of competent hackers and not much chance of people being able to afford legit games.
