There's a really good article about this at Anandtech but I'm afraid it's time to rein in expectations. This isn't going to replace either your DRAM or your SSD any time soon.

Key Points:
- The 10x density is of DRAM rather than NAND so the density compared to NAND probably isn't that great. In fact according to Anandtechs best estimates it's a bit lower than planar NAND. They are also expecting significantly higher per GB cost so it sounds like the dream of an ultra fast multi TB SSD at consumer level pricing is dead for now.
- Latency is higher than DRAM and while not clear on what the bandwidth will be, it's probably going to be lower than high speed DDR4 and certain to be lower than HBM. So a replacement for DRAM is also off the cards for high end gamers. Also the DRAM modules are initially only being released for Xeons and the timescales for that are unclear.
- It's being pitched by Intel and Micron as an additional hierarchical step between DRAM and NAND, so for a consumer grade PC it's going to add to your systems cost and complexity while the benefits are likely to be not hugely noticeable. If you can afford enough capacity to completely replace your SSD though, then it should be pretty nice - albeit hugely expensive.
