They are building a "Monsters. Inc." attraction in that space.
I really liked Timekeeper. It was developed at the same time they built one at "EuroDisney" (now called "
Disneyland Paris").
They stopped operating the one in France long ago.
WDW version opened in 1994 and closed permanently on February 26, 2006.
Sorry to see it go.
I think that it would be a better "match" to the park if they moved Timekeeper to Epcot.
Its theme of "bridging between the ages (and the world locations) would be a great addition to the FW/WS connection.
