Epcot's attendance peaked in 1987, again in 1997 and took until 2017 to surpass that. The piecemeal approach isn't the solution either. The attractions of yesterday needed to be replaced/updated, but the themes did not.
Look at the dedication plaque for guidance:
To all who come to this Place of Joy, Hope and Friendship
Welcome
Epcot is inspired by Walt Disney's creative vision. Here, human achievements are celebrated through imagination, wonders of enterprise and concepts of a future that promises new and exciting benefits for all.
May EPCOT Center entertain, inform and inspire and above all, may it instill a new sense of belief and pride in man's ability to shape a world that offers hope to people everywhere.

Celebrate discovery, celebrate cultures, inspire greatness and aspire to be better. Nothing that was announced today for Epcot, including the fanboi interim show, Epcot Forever satisfy any of these things.
Don't get me wrong, I'm excited for the interim fireworks show, but I'm increasingly devastated that current management shows zero understanding of what made Epcot a success. It's future is questionable at best and disastrous at worst.
