It's not on the plans which were leaked last year, and with the capacity being quite low already, I doubt they'll use it. It would be good to have it, but Fastpass can cause more problems than it solves - it doesn't add capacity, it just shortens some waits and causes a lot of hassle. It'd be a similar situation to Peter Pan's Flight actually, with fastpass tickets gone within hours and massive queues for the normal line all day long. I know I might regret this if I'm waiting hours for the ride next year, but I think they made the right decision here.
I reckon at the end of 2007 we'll have Rock N Roller Coaster and Tower of Terror as the only fastpass attractions, and then when they've completed the redo/extension/re-arrangement of the Tram Tour they'll add it back in there as well... just a guess though. :wink:
