I don't know how could AMD keep Fury as their high-end cards with only 4GB. That's why I think (or hope) that the 490X will be faster than Fury and around GTX 1070 levels of performance.

Also, I think that AMD has Vega up and running, but they are waiting on HBM2 prices to fall down to launch it. They expect it will happen early next year, but if it happens before, they could release Vega late this year.

Having 4Gb is certainly a hinderance over the long term.
However... They were limited technically, HBM was new, AMD was on the cutting edge, they wanted to repeat the same success they did with the Radeon 4000 series, unfortunately HBM wasn't there all the way.
HBM2 things will change, larger capacities, more bandwidth... And then in 2017/2018 we should see the successor to HBM.

AMD will also be releasing a 200-300w APU with HBM, which should run rings around the PS4.

The big problem of HBM is that using the 1024-bit bus per stack take so much traces that AMD and Nvidia are only able to use 4 modules. Even the GP100 was only using 4 stacks, but of HBM2.

I wonder what that HBM successor might be. Has anyone heard anything about it?

That APU you talk about... I find it hard to believe it, to be honest. Not only because the first mention of it came from Fudzilla (at least, if you're talking about that 16 Zen cores + Greenland + HBM rumor) but because not even AMD would launch such a power hungry APU. It would need to come bundled with a CLC unit and that would make it too much expensive to make it a worth buy over a separate CPU+GPU, that could use less power and be even faster.
