Speaking of the Avengers E-Ticket, it sounds like Disney has a particular approach when asked about it...
I know parks have played the "Ride, what Ride?" approach, but that's usually for attractions that haven't been officially announced or mentioned. Considering this one has been mentioned before and they're now acting like it wasn't, I really wouldn't expect to hear much about it for a while.
To make things more perplexing, they're doing the same to the Black Widow/Black Panther/Taskmaster stunt show which actually performed with the land's opening...uhhh, that's a new one.
