they do the same thing with every console and most tech which requires updates, build system with limited memory, update until the memory is filled, device no longer properly functional forcing you to buy extra storage space to keep using the product or buy an updated version of the product with better more space

Shockingly it not to make you buy one of thier proprietary memory cards this time around

Because nvme is expensive. Even on a pc it's expensive, but at least you can upgrade as you go.

For comparison, you're looking at about £150 for 1T of nvme storage. The ps5 digital version is £360.

The entire ps5 costs less than a 3T stick of nvme lol.

Because they WANT YOU TO BUY THE PS6 next when every download is 85gigabytes soon.
