That's what they said about GDDR5, being too expensive at the time.

Difference is... GDDR5 was in low-end and mid-range GPU's (Like the Radeon 6570, 7470, 7570... Geforce 440, 450, 545 etc') before the Xbox one and Playstation 4 launched and even then only the PS4 launched with it.
HBM is only in the most premium and the most expensive GPU's such as Fury and Vega and a few Tesla cards.
HBM chips aren't the only cost-issue you have either. Interposers add an additional cost.
GDDR6 is going to be cheaper than HBM anyway and scale fairly well.
Hynix also disclosed it has a partner lined up for it's GDDR6 memory on a 384-bit bus... And it will have 768GB/s of bandwidth and probably a 12GB memory capacity.
For comparison sake... HBM1 had 512GB/s and HBM 2 has 409GB/s as per AMD's implementations.

Again... I state that HBM is unlikely going to be a thing for consoles. It's to expensive and the alternatives are likely superior.

Sure GV100 is the next gen, for supercomputers that is, something that costs in the 4-5 digit numbers. We're talking next gen parts for consoles.

I don't think you fully get it. There is this thing called "Moores Law".
GV100 is probably launching *this* year. On a "custom" 12nm process. (With a 14nm BEOL or FEOL.)
That kind of performance should be consumer-level stuff by the time next gen is here and we are at 7nm. The PC doesn't stop progressing for anyone.

Doesnt really matter what the low end is doing, what matters is what technology is going to be the standard. If industry is moving to HBM2, then that will be the logical choice as it'll get cheaper over time. If AMD's high end product line up consists of HBM2 onward, it should come to consoles as well. 8GB GDDR5 was expensive at the time, everybody was surprised they went with it, even Epic's Mark Rein. It all depends what the next technology is, if GDDR6 emerges as the winner, then it should be that.
"That kind of performance should be consumer-level stuff by the time next gen is here"
But not by the time a console would launch in fall 2018. For the best, AMD's Vega will be more than enough to start next gen. A console with equivalent GTX 1080/Ti performance in 18 months will blow everyone's socks off.
