I would even settle for them telling us right now in 2017 that it won’t be completed until 2020. Again, that would at least be something.
It has nothing to do with 2020. Despite the distribution rights deal, this is just an arbitrary excuse date you (and others) have assigned to the issue.
Disney has no plans to restore the OOT. None. It should be painfully obvious by now that Lucasfilm and Kennedy have discretion on this question and they simply don’t care.
