"anyone have details on what they're doing?"
I don't know anything about Epcot on the 5th, but I do know that they are having a similar event the day before, May 4th, at MGM for a press preview of the new stunt show. My friend and her husband are annual passholders and they got an email inviting them to submit an essay for a contest where 50 passholders and their guests will get trips to WDW and passes for the media event on 5/4. Sounds like they are doing something similar at EPCOT.
