HEA is intended to run alone.
I have no qualms over sharing two pieces of information:
1) They decided they don't WANT to run a new nighttime parade for now. HEA didn't force that. They don't want to run a parade.
2) As such, HEA received considerable investment and its strong pyro budget.
The upside is all this is they still plan on a novel nighttime parade in 2021 but our nighttime spectacular infrastructure went from being the weakest to arguably the strongest among Disney Parks. We keep all that tech, which should allow for truly dazzling 50th entertainment. While I dismiss offhand the idea that the company cannot afford these fireworks and a parade in their most-visited park, our infrastructure upgrades in the hub area in recent years are phenomenal and a serious investment in the future of the park (if only the lighting was retractable!). While we may question some artistic direction, we are now seeing the effects of a renaissance for WDW.
Again, I don't agree with the idea that there were only two choices (rush a nighttime parade and give us a "pretty-good" nighttime spectacular or give us arguably the greatest firework and special effects spectacular the company has ever produced, I'd rather they invest 100% in one concept (as they've done with HEA) and focus on the parade later. Of the two options, that gives us the best products overall.
