Hynix announces that they're building GDDR6 memory for a high-end video card in early 2018.

And probably enough specs on it to make someone mad. Apparently the unspecified upcoming GPU has a 384-bit memory bus, with the memory rated at 16 Gbps, for 768 GB/s of memory bandwidth. Hynix says that it's coming in "early 2018".
Nvidia has made lots of GPUs with a 384-bit memory bus, including the GeForce GTX 480, GTX 580, GTX 780 Ti, GTX 980 Ti, and GTX 1080 Ti. So one could have guessed a top end GeForce card with a 384-bit GDDR6 memory bus would show up at some point. That vague guess wouldn't tell you the timing of the launch, however.
AMD, meanwhile, nearly always goes with powers of 2 for their memory bus width. They've only made one GPU ever with a 384-bit memory bus: the Tahiti chip of the Radeon HD 7970/7950. And with AMD having already announced a move to HBM2 for their high end, to follow that with GDDR6 would seem like a downgrade.
