Alright, I've made some calls recently and here's what I've found out about various programs:
Berkeley: The person I talked to today said the department has just given her the go-ahead to start sending out emails. There are hundreds so they will be going out in the next couple days. Side note: this is 2012...shouldn't this process be automated by now?
Boston University: The person I got ahold of last week said that, due to a family emergency, the head of their admissions committe had to leave the country for an unspecified amount of time. The admissions decisions must wait for their return.
Colorado Mines: Their deadline for notifying accepted students is April 15. So, expect a decision by then.
