>> Should Games go back to cartridges?

[Lightening]

assuming cartridges can even hold the equivalent of a DVD let alone a Blu-Ray without becoming too physically large to be convenient.

we can safely assume that they can, they can hold more than a blu ray.

edit: you're probably right about the dollar cost, it will cost more to produce them. The biggest reason to say no to cartridge imo is that it will hinder backward compatibility. new consoles will have new cartridges and then we'll have to hold on to our old consoles if we want to play the old games, playstation 4 cartriges won't play on playstation 5 console for instance. discs are more convenient like that, they're always the same size.
