Speaking hypothetically... (as I doubt there is a definitive answer yet, as we know so little about it)

Seeing as Switch 2 is more powerful than Switch 1 but will still support Switch 1 games... does that suggest that if I put a Disgaea 6 cartridge in Switch 2, it'll automatically run smoother?

Or would NIS still need to do something on their end? Or it'll change nothing at all?

This is just for discussion purposes really, as again, I don't think any of us know enough about Switch 2 to actually know.
