Once the three story event space was canceled (supposedly) they obviously had to go back to the proverbial drawing board. We have yet to see those plans. So I'm just not inclined to think it will be a disaster.
We have seen this play repeatedly. Everything is going to be a disaster until ultimately it isn't.





Round and round.
P.S. The entry plaza is all sorts of symmetrical as is the monorail beam loop. That is 10x the symmetry than in all of the studios and DAK combined. And larger than the castle hub in square footage.
My hunch (and that is all it is) is that to host larger crowds in the FW plaza, the two Communicore structures and the old fountain created way to many bottlenecks. Especially after the fireworks show. Now they can keep future world attractions open later without risking safety.
Safety first.
