So that chapter basically confirmed that E.N.D. ain't a power up?? Good God, that was nice. I always disliked that idea. Now my theory that Natsu will turn to a dragon to defeat Acnologia, as it was forshadowed by the 1st conversation between Natsu and Gildarts, can happen. But damn, Mashima had planned this all along. That was a great foreshadwoing.
