Still no word on power consumption changes if any?

no word yet, but it is expected to be higher than GDDR5. It is architectural changes that give the extra speed, so it is not going to be 2x GDDR5.

HBM isn't in low supply anymore.. hasn't been for couple months. HBM2 isn't out yet so can't say it will be either
I suspect all next gen card to use HBM2 in the high end, GDDR5x in the mid-high end and regular ol' GDDR5 in the low end. Would make sense price wise for these anyway
