E-mailed the office this morning, here's the response:
Thank you for your message.
Unfortunately, as office policy, we are unable to specify the exact date in March that we will release decisions. That said, I completely understand your concern as you weigh your other options and anxiously await news from HDS. It is with this type of concern in mind that most graduate schools of religion have agreed upon April 15 as the universal response deadline, for the express reason that students like yourself will not be forced to make tough decisions without having heard back from all schools. While other schools might pressure you to respond sooner, most cannot officially require you to commit before this deadline. I would encourage you to remind any such schools about this universal policy, as we will not be releasing our decisions any earlier than mid-March.
Please do not hesitate to reach out if you have any further questions
I think it's safe to say we will have at least the weekend to ponder what our future holds, or at least ponder whether or not it will include Harvard.
Enjoy the weekend!
