Jedec DDR5 & NVDIMM-P Standards Under Development
JEDEC announced that development of the widely-anticipated DDR5 (Double Data Rate 5) and NVDIMM-P Design standards is moving forward rapidly. Publication for both is forecasted for 2018.
JEDEC DDR5 memory will offer improved performance with greater power efficiency as compared to previous generation DRAM technologies. As planned, DDR5 will provide double the bandwidth and density over DDR4, along with delivering improved channel efficiency. These enhancements, combined with a more user-friendly interface for server and client platforms, will enable high performance and improved power management in a wide variety of applications.
As demand for DRAM capacity and bandwidth continues to grow within systems, Hybrid DIMM technologies such as JEDEC NVDIMM-P will enable new memory solutions optimized for cost, power usage and performance. Adding to the existing NVDIMM-N JEDEC standards, NVDIMM-P will be a new high capacity persistent memory module for computing systems.
In addition to the previews at JEDECs Server Forum, JEDEC plans to host in-depth technical workshops on both DDR5 and NVDIMM-P to facilitate a better understanding and faster industry-wide adoption of the standards. More details will be available on the JEDEC website later this year.
Mian Quddus, Chairman of the JEDEC Board of Directors, said: â??Increasing server performance requirements are driving the need for more advanced technologies, and the standardization of next generation memory such as DDR5 and the new generation persistent modules NVDIMM-P will be essential to fulfilling those needs.â? He added, â??Work on both standards is progressing quickly, and we invite all interested engineers worldwide to visit the JEDEC website for more information about JEDEC membership and participation in JEDEC standards-setting activities.

This is great maybe we'll see some ddr5 in the mainstream market around 2020ish and I might be able to skip going to something with ddr4 entirely.

That will depend on what happens in the next 2 years with games, core count utilization and what you use your computer for. Many games are starting to struggle with only 4 cores and benefit from 6 or 8. That said, depends on what games you play and what devs will be doing in the next 4 years until DDR5 is available cheap.
I'll probably get a new computer next year, depending on what I've said earlier.

Any chance this might remove any bottle neck while playing games (least memory bottleneck) due to the speed these DDR's are going to be going at, I'm assuming that they will go 6000-7000mhz+ in speed if they are comparable to GDDR5 speeds
Just like GDDR4 looks like DDR4 didn't stick around for too long
and here i am still stuck using DDR3 and this is announced D:

Will your current computer last another 3 years though? Realistically you could probably expect it being more like 2021 for it to go mainstream, there's also the consideration that their may be something else beforehand.
Current roadmaps for CPU's don't really 'allow' for it per se. AMD will have Zen+ next year, followed by the Zen+ successor (rumoured on AM4+ socket), followed by another another variant. These are in roughly a year release, which would make the final Zen released in 2020.
For Intel, the intented Skylake replacement, Cannonlake, doesn't work for high performance chips, hence the need for Kaby Lake. Further to this they've added Coffee Lake, which is supposedly due in the second half of this year. Due to development time, it is quite possible that it won't be released until 2018. Further consideraton is Kaby Lake only just came out, I don't think people would be two accepting of two architectures in one year, since Coffee Lake will probably require a new chipset for best performance? The true Cannonlake successor is Ice Lake due in 2019, which would further suggest Coffee Lake will be in 2018, to keep with a yearly update cycle. Succeeding Ice Lake is Tiger Lake, due in 2020, which is an updated Ice Lake (kind of like Kaby Lake is to Skylake).
The reason for this spiel is that both Zen and Intel's roadmap ends at the 2020 year cycle. Adding DDR5 will require architectural changes, new interconnects for the speed, new sockets, new motherboards, and other changes. I don't see them adding these to non-major architecture upgrades like the final Zen in 2020 and Tiger Lake in 2020. This would point to both AMD and Intel having it on their 2021 processors, if they still do desktop processors then... Intel are also looking at dropping x86 code, I presume they mean native x86 code and possibly older, redundant SSE instructions etc. AMD would likely do a similar thing, both in conjunction with adding new instruction sets. This doesn't mean it won't run, it would probably be done through some UEFI based emulation using a new instruction superset. If this did happen, and a variation of it will at some point, it will probably be with the 2021 processors.
All this points to 2021 being the year for DDR5 and other changes, and also it being a huge year in CPU tech (unless it is delayed until 2022).

well thats welcome. i would like to see so-dimm and desktop ram sizes to be the same as to allow interchangeability.
