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.

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.
