Why are we still using discs instead of cartridges?

And I believe the Wii U discs could hold up to like 50 gb and the only game that actualy came close to filling that was Xenoblade X I think.

Wii U discs are nothing more than a variation of blu-ray, so they could use dual layered discs as well. However, they haven't done this so far. XCX is on a 25GB disc, just like all other Wii U games.

Wow so only half. Well, Nintendo apparently is fantastic at optimizing games and the space they require. I know people on this forum have gone crazy at how small Nintendo games are memory wise when they actually play the games and they feel very large and detailed for the memory size. Needless to say, if they go cartridges, I doubt they will need anything larger than 64gb sd card (if that) for each game if memory in those things works the same as it does in discs.
