The interesting sidenote related to the possible Stan Thomas transaction is what Universal is looking at in order to free up those wetlands on the East side. At some point, Universal may need its own version of the Disney Wilderness Preserve, so they might need to purchase as much as 1,000-2,000 acres or so elsewhere for wetland restoration as
@GadgetGuru pointed out earlier.
Given the development situation around Orlando (population growth is consistently high), they'll need to account for that sooner rather than later like Disney's exchange a couple years ago when they bought Mira Lago's 3,000 acres and exchanged that to free up 575 around the resort.
Universal would want to free up the wetlands between Sand Lake and Destination very quickly I'd imagine since they'd probably include that land in any designs of the early/middle phases of the resort buildout...
Though others have pointed out that it may not be feasible to touch Shingle Creek. Maybe just go right up to it.
