I've heard that Intamin reps have been at the park the last few days. That signals to me that the park wants all cars drifting the way they are supposed to at all times. Also, mechanically making sure everything is structurally 100 percent ready to go.
Universal isn't going to put up with extended down time like a SF park would. This ride needs to have significant uptime.
Other than that, it could soft open any day. lol
