It's worth noting that the real promise (and goal) of NVMe is commoditization. That was mission #1, from Day 1. The standardized interface drastically reduces the cost of R&D. In the past, all PCIe SSDs required custom drivers, etc., which requires much more upfront cost just to get the drive up to speed. Also, it complicates software support, as all software has to be a custom design.
There is a bit of truth to both statements, but NVMe is overpriced because there are too few suppliers. Thus a premium is "justified." Also, a dearth of 3D TLC products is part of the issue, but that is being addressed quickly. I expect client NVMe pricing to drop very quickly over the next few months. Don't kid yourself and expect SATA-like pricing, but the floor will drop out from underneath pricing once the current NAND shortage is alleviated and more 3D TLC NAND is pumping out of other non-Samsung fabs.
The commoditization subject also ties into another comment above, which inquires if a 8.65 percent price differential qualifies as a lower price tier. Answer: Yes, in a commoditized market, it does, but we aren't quite there yet for NVMe.
