I'm surprised there hasn't been anyone accepted or dropped off the WL this week. I guess the optimistic outlook is that if all the seats were full through R4, WL applicants would already be dropping like flies.
Waitlist candidates were told they'd be reevaluated after R4 notifications go out. There will be an email asking whether waitlisters wish to remain on the waitlist, and then the committee will evaluate the waitlist and make a decision. I would assume, based on the R3 timing, that that email will go out today or early next week and then the decision a week or 2 afterwards.
