Tech wise, the PS5 is going to use PCIE4 and an NVME drive, both are available for PC, and probably faster drives will become available as PCIE4 starts becoming mainstream; what will be interesting to know is how both Sony and MS are managing the drive's FAT, maybe Sony are using something something akin to what Apple are doing with the FAT on their devices.
LOD is not just loading, it's also available CPU and GPU resources; everything might be already in memory but the hardware is too busy processing something else. No matter how amazing the underlying hardware or engine used is, we'll still see LOD pop-ups, maybe not much as before, or at least they'll be masked by fade-ins.
Raytracing is possible right now on any device, but it's computationally intensive. The nVidia's RTX series has hardware capabilities for that, think when they created the first GeForce with hardware T&L. However raytracing is still expensive resource-wise, just take a look at the Quake 2 RTX demo and you'll see that even top-of-the line computers are struggling to get 4K60 with raytracing on with a 2080.
