I suppose in a strict sense, you are correct that the market is shrinking because medium format is not competitive. But it's not the price that is the major factor in medium format not being competitive.
Lots of people would rather have a Hasselbald instead of an A7RII, if everything cost the same.
I was doing some tests with my 1100D at ISO 6400 and Small JPEG quality. I can barely tell the difference between ISO 100 and ISO 6400, and I usually post things at a maximum of 800 pixels wide due to forum limitations, so a Small JPEG is just about perfect.
Despite this, I still want a full frame camera. Really I'm all wishy washy on the issue and have been for years, I should probably just buy a T6i tomorrow and be done looking at cameras for the next three years, but I know that Full Frame "can" do things that a crop body can't, artistically and technically. Hobbyists will flock toward the new 44mm sensors as soon as they're affordable.
