I might be wrong, but my first impression was that the Church of Russia wanted to seal the celebrations of the IF martyrdom’s centennial with this very special event, that is, the official recognition of their relics. It does make a bit of sense if you see how it all evolved. Initially, they said that they would have the results in approx. two years. Then they specified the second half of 2017 as the time for the announcements, and finally, now, they say beginning of 2018. It looks like they just kept pushing it a bit forward, so that they reach the time of the big celebrations. Well, if it’s going to work for the glory of the IF in a wider scale, within the Church, then (IMO) let it be so. I don't think it would do any harm.
