Hybrid Persimmons Future Look Great

Sometimes issues come up, are hotly debated, then get forgotten. For example, a few years ago, @Richard prepared an exhaustive list of hybrid persimmon varieties. At the time, the list was dominated by >40 crosses of three DV females x Hokkaido (male-flowering Kaki), all produced within a few years by Cliff England. Taken at face value, the list seemed so promising. . . .

Is there any subsequent information on the performance of these supposed hybrids?

Is there any further information on the supposed pollen source, Hokkaido?
