I don't see anything but Sata 3 + Mechanical HDD happening for the next gen. As prices of Nand and Dram continue to increase due to phones as well as many other things requiring them, I don't see Sony or MS implementing an SSD regardless of their advantages. Specially considering phones are just going up in storage space and ram every year.
Consoles have a limited budget that Sony and MS have to work with and they will most likely focus as much as possible with cpu/gpu power rather than storage interfaces/type. If they can get away with putting a 2TB mechanical hard drive since it will be cheaper than putting an ssd with similar or less amount of storage, they will.
PC Specs: CPU: 7800X3D || GPU: Strix 4090 || RAM: 32GB DDR5 6000 || Main SSD: WD 2TB SN850
