Macronix to Start Shipments of 3D NAND in 2020
Macronix will manufacture 48-layer 3D NAND memory in the second half of 2020, said Miin Wu, the chairman of the company, during a press conference dedicated to Macronix’s 30th anniversary. The company then plans to start shipments of 96-layer 3D NAND in 2021 and 192-layer 3D NAND in 2022. At present, the most advanced technology used by the firm to make NAND is its planar 19 nm technology that has been in use since February, 2019.
The first customer for this memory, in turn, will be Nintendo. Which is an interesting development, as it was widely reported in 2018 that Nintendo's efforts to produce 64GB Switch game cards were delayed due to technical issues. To date, Nintendo still hasn't shipped 64GB cards, so this may be the development Nintendo has been waiting for to finally make 64GB cards available.

Larger carts were planned to be available to third-party developers in 2019 but that did not materialize, either.
I haven't kept a close eye on the total size of Switch games so far, but larger carts is definitely a good thing.
