So, Busch Gardens filed drainage plans with the Tampa Gov't earlier this week showing off the proposed improvements for the 2016 attraction that's going into the former Tut's Tomb building/surrounding Egypt area.
Unfortunately, since these are only drainage plans, the attraction itself is not represented anywhere on them. However, it does give you a good idea of what the area will look like, and it strongly suggests that the addition is going to be a coaster, perhaps even with an indoor/dark ride element.
Here's a full image of the plan:

To help visualize what's going on, I made this crude overlay:
Basically, they're expanding the Tut's Tomb building by roughly 11,600 square feet, re-routing the railroad tracks, adding three new trenches, and a nice new path. I attempted to show depth in the trenches by using darker greens the deeper they got, so that's what that mess represents. I'd imagine the trenches will be for the new coaster track, a la Cheetah Hunt... one trench even dives under the re-routed railroad. Also, not pictured on my overlay, but visible on the plans if you take a closer look, are several maintenance stair locations. I'd assume those would be for easy access to elevated portions of the track. The entire project covers 2.65 acres, and there seems to be plenty of room for a nice coaster section on the far side of the new path. Here's the official description of the project from the permit:
On behalf of our client, Sea World Parks and Entertainment LLC, this is to request for Environmental
Resource Permit Modification for the BGT- 2016 Attraction. The 2.65 acre project area is located
within the Egypt attraction area of the Bush Gardens Tampa theme park. This 149.79 acre theme park
is bound to the north by Bougainvillea Ave., east by N. McKinley Dr. (40th St), south by E. Busch
Blvd., and west by N. 30th St.
The proposed project calls for the removal of approx. 28,349 s.f. of existing concrete paving and the
expansion of the existing museum building by approx. 11,605 s.f.. The project also proposes the
construction of approx. 40,751 s.f. of new concrete walk and trench area. This results in an
approximate 12,402 s.f. impervious area increase from the existing condition.
Finally, here's a link to the project:
