Judging from the position of those footings, they've really cut into the Riddler/Hall of Justice courtyard. I wonder if that will leave enough space there? It doesn't look like there's any space to walk between the pylons anywhere.
As things didn't come out at the end of August, I wonder what's the reason for Six Flags Corp not announcing the single rail. Could they be holding the announcement for a more opportune time, like DC Fandome? Maybe have it as a panel so they can talk in-depth on the coaster and the theme? I've been thinking about this for a while; as it could make sense. Especially if it's going to tie into a upcoming film.
