So heres my prediction:

Natsu will not be able to kill Jacob because August gets in the way. Natsu will fight August and Jacob at the same time, but he will be outmatched. Right before Natsu is going to loose, Makarov will use Fairy Law or something and break the spell, and poof all of Fairy Tail will reappear. Everyone will fight August and Jacob together. Fairy Tail will win, but be exhausted. Zeref will then enter the room and say some crap like, everything went according to my plan. Mavis isn't the only tactician out there.
