here is another prediction :

fairy tail : maybe zeref will tell natsu something about his past and zeref wants natsu to kill him yeah. but maybe something unexpected will happen, which conclude natsu to choose, that his beloved guildmates will be live or die right now in the manga next chapter. so, some time later, natsu will realize his true beloved person will be in danger etc. and this will be the true scenario for the point of plot this manga.
