I think the argument is that QLC storage that can saturate a PCIe 3.0 bus is "good enough" for plenty of otherwise insurmountable problems (loading times, streaming incoming assets for things like Spiderman flying through a city).

Cost and the inevitable much bigger storage requirements can't be ignored. PS5 appears to be going for 4k (with rumors of 8k) resolution and 4k texture DLCs have been seen doing 50G on their own. Building a PS4 sized storage unit is fine for playing PS4 games, but once developers stretch their legs in a 4k world, you are going to need a much bigger storage system.

Marketing is going to marketspeak. Engineers have to balance many things, and storage size is going to be as important as speed (and cost is always a spec). PC NVMe speed is high enough that it is unlikely that anyone will tell the difference between NVMe drives while gaming (especially if they can saturate 4xPCIe3.0).
