Not only has surveying been seen behind Jungala and SandSerpent, we've seen physical survey crews in the park basically everywhere between the Nairobi Train Station and SandSerpent facing toward Serengeti Flyer, which lines up with the "Jethro Phase 2" theory. And as far as I've known thus far, Jethro Phase 2 includes a new Intamin LSM coaster.
