Most ccTLD registries do not have "the same economic interest as Afilias and Verisign", they steward a national resource in the interest of the national community (however defined locally). In many cases, money is just a nice side product. In general, you completely miss the point by reducing this issue to a mere economical debate. The need for prompt introduction of IDN ccTLD in certain parts of the world is, first of all, social, and consequently political for the due representatives of those societies (that is, their governments). Again, the local Internet communities do not give a damn about preserving global competition, if this means that they are deprived of the chance of having domain names in their script. Competition is nice, but it is not a sacred principle. However, you could have a point if you turned the question differently: not "why do we need a fast track" but "why are incumbent ccTLD operators necessarily the right managers for these new TLDs". If I were ICANN, I would ask the local community to agree on which strings are to be introduced, and on who do they want to run the new TLD. If they disagree, as (per WSIS) ccTLDs are a country's own affair, I would ask the relevant government.
