Intel in a corporate slideshow mentioned the new 670p SSD which will be another QLC product. Most of the focus was with server oriented hardware. Intel has been developing the 144-layer QLC design which will also have additional SLC cache.
The need for RAM is necessary primarily for storing the allocation table and a transfer buffer for the serial nature of PCIe. Sequential block transfers can be buffered to keep the PCIe lanes saturated.
The more expensive SSD products are seldom used by gaming enthusiasts. The M.2 PCIe NVMe slot is well provisioned with bandwidth but the small size of the logic board is very limiting.
Given the maturity of PCIe 4.0 its likely that Intel will use a Psion controller to support faster speeds. The recent Psion E18 is very fast and it can handle at least 8GB of SSD chips. The previous 665p were offered in 1TB and 2TB capacity but no indication was make for a larger capacity.

The 670p all are M.2 2280 format. The all are using a custom SMI SM265 controller.
