Just for reference, Universal officially announced Cinematic Celebration in June 2018 and it debuted in July 2018 with media being given a show without fireworks (which unfortunately led to some criticism early on and not that many great reviews).
I understand that there are practical reasons why they delay announcements until their certain, but I'd hate to see this show not get the crowds it deserves due to a lack of promotion. Hopefully they run it more consistently day to day.
