Here is the full Screamscape article, which really doesn't say too much:
Rumor - (8/18/11) I’m not entirely sure what it is, but there is a lot of buzz coming from those planning to attend the D23 Expo this weekend about a possible new attraction of some kind on the way for Epcot. So far on my end, most of the rumor mills have all gone silent as far as the future of Epcot is concerned… with one exception. On August 8th, about a week and a half ago, after Illuminations was over and the park was emptied out, Entertainment staff stayed on to perform some kind of late night ‘Fireworks Test’ over the lagoon. The official statements issued to the general staff, so they didn’t freak out about late night pyro, seems to indicate that they were just testing some new pyro. “While some of the fireworks tested may appear slightly different than our nightly performance, please note that there are no significant changes planned for Epcot’s “IllumiNations: Reflections of Earth” show at this time.” Of course, they could have also been testing some material under consideration for a future show at another park as well. I guess we’ll have to wait until D23 to see what rises up.
