Let's see, from reading about the many, many different posts about the different rides I would guess:
Sounds Dangerous - nobody ever seems to like this attraction
Stitch - Not many seem to like this attraction
TiKi Birds Under new Management - even with the redo, it still gets horrible reviews by so many posters.
Indy 500 Speedway - yes it's a classic, but it takes up more space than almost any other ride. I can see two or three newer rides filling the space there. Unless they refurb it into a CARS attraction.
I think they are working on refurbing CoP, so hopefully that's a good sign of the future.
The Jungle Cruise movie is coming out soon, so I doubt they will scratch the ride (perhaps a refurb, though)
Swiss Family Robinson Tree House - I bet a refurb will make it more handicap friendly somehow.
