The BM Production Camera 4K EF Was in 2016 already considered done,
BMD Already released the Ursa Big, Ursa Mini 4K and Ursa Mini 4.6K. Which are ALL follow ups of the Production Camera 4K. Which is releases begin of 2014.
So it seems that BMD has disregarded support on the Production Camera 4K after 5 years. ( for a product that only had a 1 year service and support )
As there were so many upgraded versions after that in the Ursa series. And now with the Pocket 4K/6K.
I totally understand BMD. There products does not cost the end of the world. But people should understand that the lifespan of such product is 2/3 years maximum.
We often replace the gear after 2 / 3 years, not only to keep up and have the latest gear, but also because of service and support.
