I was at Cinegear, I talked to a few of the Blackmagic Employees about the URSA and the issues with the BM4K, they were completely honest and very up front about the issues that have been experienced by users.
They told me the BM4K's FPN issue is primarily from the sensor overheating, and they were very up front and honest about everything with me (they fixed that issue in the URSA by using liquid cooling, and AJA has a much larger heatsink + airflow on their cameras - hence their form factor).
The issue could be fixed by firmware, but it's not an easy fix by any means - the solutions to the problem engineering-wise generally cause other less-easily solved problems (increase fanspeed=louder fan, increase ventilation=open the internals to more wear & tear, liquid cooling=weight/form factor increase, larger heatsink=form factor increase).
I really don't think the issues ya'll are experiencing with the BM4K are really not as widespread as it seems on the forums, part of the issue that you're venting your frustrations here rather than reporting your problems to the actual manufacturer (this is a USER forum not a SUPPORT forum) or even attempting some level of problem solving yourself (I've put Ice Packs on a RED One before to keep it from crashing, there are masks out there for people to get rid of FPN etc.).
I've seen at least 6-7 BM4Ks operating perfectly, and I just talked to another owner today that I'm AC'ing for Tomorrow and Sunday who's shooting a BM4K camera.
