Gonna place a guess and say that EMH tomorrow, at least for the first 60-90 minutes, will not have virtual queue - standby only. Come 7:30 or so, they will open up virtual and require it for the remainder of the boarding passes they can accommodate for the day.
Also - boarding has been stalled at 26 for over an hour now. Here I was thinking I would be lucky and ride before 9.
EDIT - just started boarding again at 9:42
