So, is this likely to make its way into graphics cards, or is it for compute only?
From my understanding it is more of a software issue (OS and game engine) that is keeping us from having MCM gpu's in the consumer space, whereas from the hardware side they will be able to make it work once the interconnect designs like Infinity Fabric or NVLink catch up to the needs of the individual cores (which, they have pretty much accomplished now). I remember reading a Q&A with Lisa Su leading up to the launch of Navi where she essentially stated this. I have looked for a bit trying to find that exact article (I thought it was here at TPU or Anandtech but I'm not having luck) and though I was not able to, here is an article interviewing David Wang from AMD that basically covers the same thing Lisa Su did. I can't recall reading about this from an nVidia designer/engineer, but I'm sure Green camp faces the exact same issue. On the topic of this article (being that Hopper is not a consumer gpu), the following link also briefly covers the fact that in compute environments the MCM limitation is different or non-existent, and it is only in gaming that the problems arise. I'll keep trying to find Lisa's response/explanation, as it was a bit more detailed.
Contrary to what most of us in the tech press had hoped, the next-gen AMD Navi graphics cards will use a familiar monolithic GPU design as opposed to the multi-chip layout we'd hoped might deliver an efficient high-end gaming card.Most of us had thought AMD would start to use its Infinity Fabric int

More serious... So far this seems to just be oriented at other markets but eventually some cut down should reach us, especially if you consider the die sizes and power on current top end cards. Not much headroom there.
I too expect the day to come for MCM to trickle down to the consumer space. But it seems AMD/nVidia are more so at the mercy of Microsoft and game developers. It is a MUCH needed evolution of graphic card design for so many reasons. cost/scalability/yields/ just to name a few big ones.
