No decision and it's already April 7th!

I applied Regular Decision to the University of Maryland. I met all the deadlines and had no problems, yet when April 1st came around I still didn’t hear back. I called the office of admissions, and they said that there are other applicants like me who still didn’t hear back. Is anyone else in the same situation as me?

Even I dont have a decision yet. I emailed them asking why I dont have a decision, and they replied asking for my full name, Date of Birth and email-id. I’ll wait for another day or two, before I call them.

And what sort of an explanation is : “there are other applicants like me who still didn’t hear back”?
