I don't have any secondary conformation, but a reliable source said that the projected opening window should be between the first week of November and the weekend before Thanksgiving. There was no set date as of yet, but he mentioned that there was some fairly moderate push to try to have it open "as soon as possible" but he said that he has no experience with VR or how the setup process goes (I don't either). So ... he had no idea if that means they want to try to shave 2 weeks or 2 days off the schedule.
For now I'd mark it down for mid November to be safe.
