I dont think the frosch thing is just suddenly going to happen unexpected. When we get to the story arc where Frosch got killed in future Rogues world i think it will tell us that its been a year since the Grand Magic games and that it probably will show Natsu talk with rogue about it. There probably will be a big amount of build up to it before its almost time to happen. And maybe it was Sting that killed Frosch and thats why future Rogue killed him.
