In the map below, red is everything Uni now owns. A lot of what's on the East side I assume is wetlands they really can't touch.
The purple is where they're putting all the administrative and back lot stuff (maybe that will make more room for IoA and/or USO?).
Assume the big grey patch is parking, that leaves the orange area as the one big undeveloped plot not cut off by a major roadway.
That is 130 acres.
130 acres is four Volcano Bays. Or, it's one Universal Studios plus one Volcano Bay. Or, it's 20% larger than Islands of Adventure.
The MK is 110 acres on-stage, 140 acres with all the backstage included.
The blue patch is 45 acres. That's enough for another Volcano Bay and hotel. Or a new and much bigger CitiWalk. And there are a lot of other spots for lots of other hotels.
