Prediction: "Cartridges" will return for the Nintendo home console

[Mnementh]

First of all: I doubt it will happen.
Second: I think for a while, that cartridges in modern days would be better for console than optical media.

But look at the details. Wikipedia claims, that 3DS-cartridges can hold up to 8GiB of data. Bluray hold 25 GiB (single-layer) or 50 GiB (dual-layer) of data. While Bluray obviously holds a lot more data, a decent step in technology can double the capacity of cartridges to 16 GiB, while keep prices low. That is still less than BD, but I doubt most games even break 16 GiB these days. I doubt PS5 and XBox -100 will have a storage medium with bigger sizes than bluray. So cartridges may be able to hold most games.

Still, some games have detailed textures and lot of content. The next-gen GTA, Final Fantasy, Battlefield, Skyrim and so on might need more storage. But does these games hit Nintendo consoles if they provide enough storage? So no loss at all.

Cartridges hold some obvious advantages, especially no moving parts that leads to more reliability and less noise. Also they can not only hold game data, but also save-games.

So, while I think Nintendo won't do it, I think it would be great.
