There is an undercurrent here that everyone seems to be ignoring…
The Chinese production companies all operate its own channels on a certain tube-like site with popular series getting multi-million views per episode, this coincided with release of crowdsource subtitle and translation tool for that tube-like site. This was not the case even a year ago. It seems to they would just want to do things themselves now rather than licence things out to third parties (at very least, it strengthen their negotiation position, which can make licences too expensive for viki to acquire)
While I still like viki better to introduce dramas to my non-chinese speaking friends, since the subs are of a better quality and consistency, but that’s a shark in a tank of small fishes and could have game changing ramifications. Especially since viki is a K-drama focused site to begin with.
realistically, I would think drama with more idol appeal and less expensive to acquire will be the ones shown on viki. This unfortunately rules out both Tribes and Empires as well as Advisors Alliance.
