"Will this make any difference? Will it just turn out to be a glorified Pheonix lights indicent. Lots of evidence but no real turn in conviction?"
I hope it does make a significant impact, though I feel it will have not much more success than previous incidents. But overall, I think that it will serve to help seriously crank up the pressure for a long overdue official and worldwide recognition of UFO phenomena. Perhaps then this subject will get the calibre of research it so sorely deserves - and we may then learn for sure the answers to the questions that UFOs pose.
Or, on the other hand, maybe some Govts already are in the know, but those "answers" are considered to be too unpalatable for general consumption.
