This was the proposed additional land transfer that fell through (before Stan Thomas ended up suing to try to prevent a new theme park):
#1 (the Green properties on the right) + #2 (the Blue properties) would have been transferred to Universal. It looks like it's at least 500 additional acres. Stan Thomas would have kept the Yellow properties (and that Dark Green parcel) so that he'd have valuable land to build on when the 2nd resort is up and running.
Now, I'm not sure how this is all going to play out with the lawsuit still pending, but that's something to keep in mind; eventually this deal could get done and we could be talking about a 1000+ acre set of land (including SLRC).
