Tom's pricing states that the 128Gb version is going to cost $695.

You can buy that much DRAM (one stick!) for around $500, though in the form of multiple sticks.

Multiple sticks doesn't help when you're DIMM slot limited, though - a single 128 GiB stick is still a lot more than the price of a single Optane 128 GiB stick.

Also, for the sort of systems that can take Optane, you'd be using RDIMMs; a quick check shows that 128 GiB of RDIMM DDR-4 is around $800, and takes 4 slots of the typical 16 you have on a board. So Optane is cheaper than DRAM, but not by a huge amount.
