> but solid state storage similar to Nintendo Switch cards makes more sense to me

These likely degrade in 5-10 years, and have you seen the price of NAND lately? AAA gaming is going to get to be out-of-reach because of storage costs.

I don't know what the degradation for NAND storage is, but another aspect that I didn't mention in my original comment is the fragility of disc based media. In terms of scratches and other damage.

You have to treat a blu ray very badly to get a scratch in it. It might look like a DVD or CD but it's not. It is much more resistant to scratches as it has a protective coating called Durabis from TDK. Sony uses their own proprietary coating.
