This is what i think what will happen so from the last episode hiro mashima 投稿されました it ended off with natsu crying and blah, blah, blah so i think that Igneel and natsu with fight together to defeat acnologia and i think that with those two paired up they will win the battle against acnolongia. now as for E.N.D i have been doing some research and there is a theory that natsu is end. i think that is true because of pictures i' ve seen in videos. and also when i read the theory it all made sense. so im pretty sure something bad will happen because i honestly think that natsu is end. im not saying he really is but i think. i honestly dont want natsu to be end because it probably will get in the way of nalu. and yes i am a ナツルー fan. now back to my point i think even though it is a bad thought of natsu being a demon i know something good will happen. im sure if he really is end then im positive natsu wont be end forever. what i mean is that he can hopefully conceal that power and live normally until he actually does have to use that power. i know that right now the series it shows that everything is horrible but i know that it will end out good. i know this because hiro mashima stated that fairy tail will end in a good way. and also he 発言しました that once he finishes that series there will be another one.
