Looks like it's finally starting to arrive:

http://techreport.com/news/25838/sk-hynix-has-an-8gb-lpddr4-chip-too
Both chips seem to be running at the 'starter' speed of 3200Mhz delivering 51.2GB/s in a typical dual channel configuration.
I'm more interested on the apparent peak speed that should be arriving a little later of 4266Mhz delivering 64GB/s on a dual channel interface or a massive 128GB/s on a quad interface like those of the E series Intel CPU's.
I wonder how long it will be before Intel CPU's officially support this speed of memory. I'm guessing a while. The first DDR4 supporting Intel CPU sounds like it'll be either Broadwell or Haswell-E, both of which I expect to support only 3200Mhz. Then again, it would be in the interest of Broadwell to support the faster memory (if it's available by then) to support the IGP.
I'm also hoping for a doubling of the Crystalwell bus in either Broadwell of Skylake. That combined with dual channel DDR4266 would deliver a memory subsystem very similar to that of the Xbox One - which would be very cool for what is essentially a mainstream level CPU with an integrated GPU!
