Carts are expensive, they get more expensive based on storage space. Frankly, publishers would obviously like to avoid producing them.
Yeah, up until 8GB it's really cheap, but then it starts curbing upwards. 16GB should be pretty cheap too nowadays, with 32GB however starting to become expensive. 64GB, while technically very possible, would eat to much of the profits to make then viable right now.
On that note, Optical dics are also getting more and more expensive since they are getting less and less mass produced. With movies increasingly coming in digital form through the internet, the demand for Blu-Rays has been dropping for years, making the production more expensive in turn. In other words, for smaller capacities, Switch cartridges should slowly actually become cheaper than Blu-Ray Discs in the smaller categories (4 and 8GB).
