You'd be surprised how many team members aren't as aware as you would think. There's a chunk of team members that really only know IFFF is closed, some because they're more focused on potter, some more focused on transformers and some don't care at all (they'll find out when it's announced). Some know it's obviously going to Simpsons but have no idea what or when or how fast.
The man reason for all of that is most team members don't come to the park recreiationaly often, and their walk to their venues don't take this past this work at all.
