I would normally equate not hearing something back by this point as a rejection. In my experience, I knew that I was going to be admitted long before I got the actual "admittance" package from the department or graduate school. Plus, through contact with my POI, I know that I have been unofficially rejected at several programs even though there hasn't been any official correspondence.
Hate to be a downer but I thought I would try to give you an idea of what my experience has been.
