I hope the title is explanative enough of what I am trying to get across here. I'm basically asking how possible/expensive would it be to create a storage PCB exactly like the one found in the switch but instead of having the BGA pinout for an EMMc Chip it would have a pinout for a UFS chip or an EMMc chip that has a capacity larger than 256GB. I'm asking not because most people are going to fill up a 2TB MicroSD worth of games but for the future, since they plan on supporting the switch until around 2023 or even longer, technology may progress to where 2TB microSD cards are in fact a thing but they are way too expensive to purchase for the average consumer. Also, I'm just curious to know would it even be possible. If anyone knows anything please let me know it will be very much appreciated.
