Both the PS5 and Scarlett sound like a console implementation of AMDs Radeon Pro SSG.

The Radeon Pro SSG has a PCIe3 x8 NVME SSD on the GPU PCB directly connected to the GPU and managed by HBCC which uses the 16 GB HBM2 memory as a first level cache to the SSD.

I haven't had a console since the PS2 but the promise of a unified memory pool with GPU decompression (or dedicated hardware like in one of Sonys patents) a desktop class CPU and an SSD as the baseline (~100x better latency, ~40-50x better peak read etc. and games hopefully not developed with a HDD in mind anymore) looks really promising.

Sadly the GPU increase will probably be eaten up mostly if they go for native 4k.
