I've really hoped to see them in the next months as the rumors speculated, but I got a feeling they will release next year.
Complete specs are still unknown, but rumors say, that the GDDR6 RAM could be faster than HBM2. I can't wait to see more about it and how big the leap to current gen will be. I guess they will announce more in august.
