PC DDR4-SDRAM Surfaces on JEDEC Roadmaps
PC DDR4-SDRAM, the successor standard for DDR3-SDRAM, which continues increasing memory bandwidths while maintaining the same electrical footprints, surfaced on JEDEC roadmaps, at a recent MemCon conference in Tokyo, Japan. Just the target clock speed range for DDR2-SDRAM was 400~1066 MHz, and that of DDR3-SDRAM is 1066~2133 MHz, the DDR4-SDRAM standard will aim for clock speeds between 2133 and 4266 MHz, with DRAM voltages of 1.1~1.2V, the voltages standards-compliant DDR3 memory will ultimately end up with. Some of the first DDR4 memory chips will be built on the 32 nm or 36 nm manufacturing processes. JEDEC expects sampling of the new memory type to start in 2011 for the industry to come up with appropriate memory controllers and deployment platforms, while actual mass production is slated by 2015.

Mass production not till 2015 though, damn that's a long while.
At least this is far off... phew...
Anyway, since they will release this in 2015 I can imagine myself getting them in 2016~2018 because the same thing that happened with the DDR3 will happen again, I mean they will be extremely expensive, so I'll wait 2 o r 3 more years until I buy some of them.
I still have yet to jump off my DDR2 s775 platform!
In terms of hardware. memory has not kept up with the over all speed that the other parts of a computers has been upgrading to.
and GDDR4 is not DDR4.
