If they want to get a GPU that size in, they are going to have to skimp on basically everything else most likely. HBM2 aint viable at that power draw, and CPU wise, who knows how Zen will shake out.
If we consider 200w the maximum limit, that's going to really seal the deal unless they want to end up with heating issues and other problems.
TLDR, expecting a full generational leap is nonsense, they are going to go for smaller jumps more often. That is what they stated
You have it the wrong way around, HBM2 is vastly much more power efficient than gddr5
Using 8GB of HBM2 instead of gddr5 , at the same memory bandwidth, will save them a good 30-40watts in system power consumption.
GCN is also laughably power inefficient, a maxwell gpu with the same performance as what's in the ps4 would only have about 60 percent of the power draw.
So there are huge gains to be made performance wise (different architecture, 2x power efficiency from 28planar -> 14nm ff+, save at least 30W from using HBM compared to gddr5)
6TF on amd means r9 390x performance, which you can get for like 120W with polaris, less if it uses HBM2
