I think the opposite is the case, keycards make much more sense for small titles that are quick to download and don’t eat up lots of internal space; also, smaller cartridges will probably cost more for what you get instead of less when buying in bulk. Production capabilities for smaller sizes are on their way out for anything smaller than 64 gb except for specialized storage with super high speeds. In the microsd-card market there is a noticable bump in cost/gb when stepping down from 32gb to 16gb, so i assume that the 32gb will already cost more in bulk for new orders.
Hmmm thats another way to look at it, you might be right.
But game sizes are getting larger and larger - at least in the AA - AAA area; Maybe Nintendo doesn’t want to get locked into a contract for a good that might not be useable? logistics might also be a reason, not having to handle one more type of cartridge.
