I would bet you... and this is just my hunch... that if they do decide on an 11/1 launch, anyone with stays from that day on will be able to start reserving FPs and customizing their MagicBand by 10/1. I would bet that at this point they have a date decided on and it'd take something big to push it out. They know where the system's issues are by now and this new round of testing that just opened up is more likely to confirm resolution of key problems they believe they've fixed. I'm no insider but having spent years in Project Management, it just feels so similar to how most I've ran have panned out.
