Ok, I got some interesting info on Manta today, from some park spokespersons at the Scout Fair in San Diego.
-Forbidden Reef is gone for good, it will not be returning. Manta will be taking up it's area now.
-The Mantas have been moved to the Aquarium in the Journey To Atlantis gift shop for the time being.
-A large section of the back of the park will be closed for the next year, so watch out for bottlenecking over by Shipwreck, especially when One Ocean gets out...
-Construction has already started.
-It is unknown whether or not the Bat Ray feeding will return in this new area. Odds are not in its favor sadly :(
- The queue and gift shops will have aquariums.
