HELP! Internship application decison "on hold"

SO a few weeks ago I had an had first and second (final) round interviews with a BB at my school. This is a position I really want. The final round interview was thursday and friday evening at 5:30 i received a call from HR saying that they basically loved me but because the internship is so competitive and due to the needs/circumstances of the company that my application was being put on hold until April. As far as I know no one else from my school was accepted. What does this mean?? I have been told that the fact that I was personally called and told, rather than emailed is a positive thing. I have already followed up with HR continuing to express my interest and enthusiasm for the position. Any advice on how to seal the deal and land this/ what this means??
