Knowing Universal, would you really be surprised if they put coaster track out in front of the Discovery Center (like Rip Ride Rockit in front of the facades,) or over pathways with nets (like Flying Dinosaur?)
The area in question is nearly as big as Camp Jurassic. You throw in some supports that branch out in different parts of the land and you got yourself a coaster... Especially if it's more family (Coastersaurus at Legoland Florida) and less thrill ride (Lightning Rod at Dollywood.)

Of course, it's always possible that the new attraction will not be a coaster. We really do not know.
Gentle Giants Petting Zoo anyone?
