When the "re-energized" version of Captain EO replaced Honey I Shrunk The Audience in 2010, it was supposed to be temporary. A lot of single white gloves have foated ubder the bridge since then. At this point I think it's safe to assume that HISTA will never return...and I feel that many of you would agree with me that the time is long overdue for a replacement attraction.
I'm thinking that it might be time to dispose of the building and make way for a new attraction and genra. One such possibility would be a new generation tech version of The Magic Kingdom's Stitch's Great Escape.
