Perhaps the reason they are so undecided on the replacement is because they are actually concerned with the thematic balance of Tomorrowland? I think it’s quite ridiculous to say that Disney never listens to the fans. They often do, when fan opinion has merit. It seems like they actually care about this update to Tomorrowland, so they’re taking their time with this replacement. Why waste money replacing the attraction with another cheap ride, when instead they can take a few extra years making something truly special (or at least good by Disney standards). Why would they rather have nothing in the mean time instead of an operational SGE you ask? Simple. The ride was so unpopular, it probably caused too many complaints for it to be worth keeping it open. Complaints were even common in the Alien Encounter days too. The easy solution was to just close the bad attraction. If there’s no bad attraction open, who’s going to complain? (Disney fans of course). Anyways, that’s enough of my rambling theories. Back to discussing the topic at hand.
