Definitely it will be ST2 leaving all others ,if Vadirocks information is correct,it is my sure guess as DishTv plans to sell new connections in Tamilnadu with ST2 as sattelite for recieving D2H Tamil channels.They may use GSAT 15 for getting free DD channels,they may give this facitity to all who have dual LNB or monoblock LNB or to all those who invest in new LNB,otherwise they will get only D2H channels from ST2 sattelite in DishTV box
