What elements of next gen could the Switch's successor implement?

They're limited by the carts not the card reader, no? They could make new carts but I don't see that happening.

I'm not saying they'll ditch the hybrid, I'm just pointing out what it takes to beat a hybrid. Even handhelds can't compete so it will take a lot for a home console to beat hybrid sales.

Nintendo could use PCI-e 4.0 express lanes if they really want for a cartridge solution, that would make the cartridge blazing fast. There are new hyper-fast SD Cards that are doing that, Nintendo could likely do something similar for their cartridge slot if they really wanted to. Ironically this is probably something Nintendo of the 90s would prefer. It wasn't really a big deal last gen because many devs are still running games off a Blu-Ray disc at the time and the Switch was faster than that, not much point in going overboard. 

I'm talking about improvements I want for the current Switch.

If I had a choice between a combo, I'd choose a Switch 1 hybrid and a Switch 2 home console (2-3 years earlier than a hybrid successor) over a Switch 1+2 hybrid 2-3 years later.
