Then there was the unfortunate breakup with Sinar, Jenoptik, and Leaf, with DHW as the only party still interested in the continuation, but perhaps the one with least support. Then there were the 80ies with less than desirable quality. US representation at that time was also less than desirable. All of this has now been solved though.
At this point, ability to use the 50MP Sony sensor, perhaps in Leaf incarnation, would be important. If they could talk Leaf into once more making a Hy6 version of their Credo 50...
Alternatively, a start-up company designing a less expensive 6x6 sensor would get them once more in the spotlight.
