Busch Gardens Tampa Bay

Recently visited the park last weekend and was just wondering what all the construction is for.
Not Rhino Rally But the area behind Kumba and the Congo River Rapids. Does anybody Know why there is construction back in this area? Could BGTB have another big surprise coming? If you go to the GLB's coasterzone linked in the news section you can see that there are two areas of construction. Any thoughts?

I thought that is where Rhino Rally is going.

No Rhino Rally is going in the large area that is across from where the elephants are. The train ride takes a loop around this area. The area that I am curious about is in the back corner of the park behind the Congo Rapids and close to the python. It has seen minor construction I believe one of the retention ponds was removed and the land was leveled out. It maybe just a staging area for Rhino Rally but just wondering.

BGT is my favourite park. Fill me in -what's Rhino Rally? I'm going in August to ride the best coaster ever, Montu of course. Whats your favourite coaster at the park? Montu, Kumba or Gwazi??? Obviously not Scorpion or Python- soon to be demolished.
