Maybe I'm biased, but I don't see Flight of Fear going anywhere. The building is in good shape and would be expensive to tear down (just look at Tomb Raider), there is also a whole crane system in the ceiling for assembly of the ride. It's very integrated into Area 72, removing it would mean reshaping the whole area. FOF is also for the most part a crowd pleaser, I've seen a lot of people get off the ride laughing and saying it was worth the wait. The long line can be attributed to its poor capacity, but people still wait for it. People also go wild for the launch out of the station. I believe when FOF's time has come, it will get new track, supports, new more accommodating trains, and an updated launch. Maybe we could see a layout change, but for the most part I think the building and all the infastructure will stay.
