Of course. An investment of this size needs careful consideration. What makes you think that Universal haven’t already committed to the amount of land they need for future-proofing?
There’s another parcel of land to the south of the site that they purchased which is, or at least was available for development and was actually owned by the company, Cloud Wing, that they purchased the land from that they now own. Why do you think Universal didn’t buy all of that land? I think it’s likely that some of the land that Universal own, probably the upper tract of the northern parcel of land, will be using for developing residential housing, which suggests to me they are well endowed with space. I suspect that Universal have a reasonable idea of their future land needs and are content with what they already have (including the option to acquire some more).
