Hmm. The Exakta had an an unparalleled system and was approximately the top 35 mm SLR until the Nikon F was introduced. What killed Exakta wasn't that catastrophe the RTL1000, it was the Nikon system and, more generally, modern SLRs, primarily from Japan. East Germany couldn't complete.
No the Exakta was surpassed by the Praktina just after WWII which was a far more professional system with motor drives, a bulk film back etc, but ultimately too expensive to manufacture.
The Nikon F had a greater effect on the Paktinas when launched in 1959, it was the first Japanese full system camera, I do'n't think it really affected the lower priced Exaktas they were still selling well in the UK a decade later. But you are right the move by Pentacon to the RTL100 couldn't compete with the cheaper Japanese SLR's which began to flood the market in the 1970's.
Given that Exaktas were make in Dresden, Germany, which was a Soviet bloc controlled (East German) area after WWII, the brand suffered from the same relative 'backwardness' in design as just about all Soviet photographic products, and probably the same resistance to market success afforded to all the Soviet bloc products.
Praktina's were far better built and also made in Dresden, more akin to a Leica in build quality, and the CZJ lenses seem better lubricated than those for the Exaktas and Prakticas.
