With the move by the latest console manufacturers to using graphics ram in their machines, how much do you wanna bet that in the next cycle (assuming there will be another generation) will use high bandwidth memory? HBM offers lots of memory density in a small area and offers high data bandwidth. Hell, why not HBM for anything that doesn't use upgradable RAM, like laptops or set top boxes? What's the likelihood of this happening?

Pretty likely I think.
Not for system memory, because CPUs aren't designed to be interfaced with it currently, but for the dedicated graphics, why not? Saves space and is high speed.

Next *Lake refresh is rumored to use an AMD GPU on the die along with a slab of HBM with it. Could spell very good performance and a move to full integration with CPUs sooner rather than later.

What's stopping them from putting a HBM2 memory controller inside the CPU, instead of a DDR4 one? I.e. 4 Ryzen cores + Polaris 10 + 16GB HBM2 for small form factor builds.

HBM is point to point. You can't use slots or sockets for it afaik.
So, eschewing the DDR4 controller would mean they couldn't have any DDR4 on the board at all. It would only have a fixed amount of memory.
Also, HBM2 is super goddamn expensive per GB.

The ps4 launched with all GDDR5 memory.
Is this different somehow?
