I've seen no indication that the program will stop. There is no reason to plan around this though unless the regular price for 3 day park hoppers will break your budget. Plan the other portions of your trip (hotel, travel, etc.) and then purchase the tickets when the 2015-2016 passes become available during the summer. If for some reason the Salute tickets are not available, just purchase the regular 3 day passes then. Bottom line, there is no advantage to purchasing the Salute tickets earlier than you have to.
