I wouldn't read too much into it. They've stated they're busy and, depending on when you emailed, it could have gotten lost in the shuffle of all the other people emailing the same question.
They emailed admissions asking when decisions would come out. I wouldn't expect to get that email if you didn't email admissions asking a similar question.
I wouldn't assume that yet. What I've seen from past years is that there are a couple waves of acceptances that go out in the last week of March/first week of April. I'm in the same boat though. Just trying to hold out hope things align with last year.
