According to cast members at the Magic Kingdom and EPCOT, they have heard that fireworks would be back in both parks by or around July 4th.

Obviously, July 4th is a popular night for fireworks viewing at both of those parks, as typically, special shows or end tags are offered to guests for the American holiday.

As for what shows would perform, the expectation is that Happily Ever after will return to the Magic Kingdom, while EPCOT would temporarily run EPCOT Forever or have a very unexpected debut of the new show, Harmonious.
