Actually, I really hate to be the one to say it, but some of us got clarification on what that email meant.
The school overaccepted (by how much, I don't know). They sent out offers, and actually got too many acceptances in response. This means that, as people drop out of the class, the waitlist won't be contacted because the extra acceptances will assume those seats. Without knowing how many extra acceptances turned into future students, it's really hard to say if anyone on the waitlist will ever be contacted. I imagine that if they are sending you this email, they don't expect it to happen.
My theory is that they were concerned about being underfilled due to all of the drama we've been through. Idk if that's true, just my thoughts. Like mentioned earlier, get those backup plans in motion, schedule file reviews, and take any waitlist offers from other schools if you still want to attend that school.
