Well what I think will happen is once the 7 Dragon Slayers activate Dragon Force and slay the 7 Dragons (if this does happen), Acnologia will appear and they'll team up to fight him only to be defeated in the end. And right before Acnologia prepares to kill them Igneel, Metalicana, and Grandine will show up and save them. Then they'll work together and fight against Acnologia. Meanwhile, Crime Sorciere will deal with Future Rogue.
