I have no information nor opinion on when the ride will open, but coming from the world of industrial automation, which this ride essentially is, it would not be the least bit surprising that it would take a couple of months to program and debug this thing. It's a very complex machine, with hundreds, if not thousands, of sensors, relays, contactors, pneumatic and/or servo actuators, safety systems, audiovisual hardware and software, PLCs, HMIs, etc., all subject to hardware infant mortality, all of which is designed to be efficiently and safely operated by minimum wage operators. No small task!
When automated systems are complex, the number of failure modes skyrockets to the point that debug alone can take quite a while (think ~10 engineers & technicians working 6 or 7 12-hour days for weeks), to say nothing of the programming itself. For example, a typical automotive automated production system will run in debug for ~3 weeks once the hardware is "on its feet" to try to identify the myriad ways in which it can fail. Plus, even with those failure modes addressed, it will go on to exhibit dozens more failure modes once released to the wild.
