When Outlaw Run first opened, the line went through the entire queue, including the overflow directly in front of the station that has since been taken out. It wound down all the way past The Giant Swing from what I've been told. People have been known to wait 4+ hours to try out a new coaster. I remember waiting at least a couple hours myself during that first year.
I am sure this will be much the same. There's been a ton of publicity on this ride with people from around the world writing about it. I would not be surprised if the line goes all the way to the main square this weekend. I will be in it, and I'll probably be live-updating our FB page about the experience.
