I agree with King Triton. Horizons and World of Motion were (to me) Disney attractions. The use of animatronics was a constant source of amazement for me. I miss these slow moving, visual rides. I'm concerned that Space will not be an adequate "replacement". It will be an attraction in itself. It will have a limited guest appeal. One description I read said it was guaranteed to make you barf. Is that really want we want in a Disney attraction? I think not, at least I don't.
I could hope against hope that at least a part of these "rumors" would come true. But, I, too, fell into the anticipatory trap of October announcements that never came. Another vote for I'll believe it when I see it.
