IF-- and its a BIG if-- they are adding a ride or multiple rides, expect an equal or greater number to be removed from the park. Wit the way things are going in the industry even big players like Universal and Disney are doing the same thing because they don't want to increase spending on staffing or maintenance for additional rides.
I think we will see a new ride, hopefully a fairly sizable one after years of not getting anything. I full expect along with the Parachuter's Perch being removed, the Twister will as well since it is the last of its kind and always seems to have issues. I wouldn't be surprised to see Cyborg gone as well for the same reason, and any other "orphan" rides could also be on the chopping block.
