I've just been reading Disneytheque (www.disneytheque.com), and they've posted a rumour that Armageddon - Les Effets Speciaux could be scrapped within a few years. The rumour cites persistent technical difficulties and a low guest satisfaction rate as the main reasons for the possible closure.
If true, then the attraction will most likely close its doors soon after the Tower Of Terror opens. It will then re-open as a new attraction on a similar special effects theme, allowing the Imagineers to leave many of the main technical components (such as the large gas tanks that sit on top of the building) in place. The only word as to what this new theme may be is "something that makes heavy use of fire". At present, there is no word of this actually being an official movie tie-in: it may just be a generic "special effects" type display.
I'm not sure what to make of this. It's true that the maintenance teams have always had trouble with this attraction, but then they've had trouble with ALL the attractions. And if they're going to leave most of the main effects in place, how is that going to make their job easier? (Unless their main technical worry isn't fire related.)
I suppose Armageddon is something of a weak link in the park, and it wouldn't surprise me in the least if it did realy close. If nothing else, the film tie-in is getting pretty old.
