I am in exactly the same boat.
My status changed to 'decision made' on 29 July and I have heard nothing since.
I was really beginning to worry that something was wrong.
My Timeline:
Application Received: July 2013
Med Request - September 2013
Additional info request: February 2014
RPRF - June 2014
Decision made - July 29th 2014 my decision also made on 29 july and no ppr

plz keep posting
When it gets to this stage, is it normally a positive sign that we have been accepted?
Hope we all hear something soon.
