Looking into it all day, doesn’t seem like that’s the reasoning. I don’t think it’s a shortage problem.
My guess is the needs of the park may have shifted since it was initially designed, and they may want to rethink some of the hub’s offerings, specifically on the right side (for whatever reason).
Rather than have to wait for redesigns to be ready, permits and plans approved, and work to be completed, I bet they just put it off till after the park opens… so they can open the park proper as soon as possible.
That said, the food court does still appear in the most recent site plans, but it’s not yet permitted to build, so guessing it’s postponed. Cassini on the other hand, was replaced with what looks like a gazebo, which may only be temporary until they come up with something new.
