According to what I know (I happened to talk to a senior person in Indigo in June), he told me that result of 2013 exam would come out by Sep/Oct.
But since I could not contact that person again after that, I cannot vouch if there is any delay further than that.
And about that cut-off merit list, I hope that everyone who scores above 70 gets through but I think there would be merit-list based scenario almost certainly.
