I don't think he is "dropping" anything soon. The abandoned tag will come, maybe in a few months and then he will release something again. Not before.
18c had only 6 more scenes. A few of them have been already finished according to the doc himself. Now we are 2 or 3 months over his hard dates already (I even can't remember them anymore). Nobody is/was expecting something big anymore, but still doc didn't release anything.
It is only a PART of a release we are waiting for, not a completely new release!
