As long as it is established as the final arc, and isn't as tedious a closing war arc as in Bleach or Naruto, then it can have as many chapters as it takes. I'm all up for badass action as long as Zeref and Acno are in play and we see the Dragonification of Natsu outside of the movie-canon.

@2nd anon Uh.... Acnologia basically joined forces with Zeref for a common goal. Plus Zeref is the direct leader of the new enemy, and END is the only threat to him, so yeah, I don't see how it can't be wrapped up in one massive arc. Sure, Natsu is still too weak to survive against Zeref, but as of now, taking on the Spriggans is basically taking on their Emperor. However, you are right since it hasn't been established yet, I can't say for certain if there will be other arcs before battling the 12 Spriggans. Like maybe Jellal has plans to make them able to fight Alvarez on equal footing. Still don't see how Acnologia can fit in anywhere but the finale, unless of course they go on a quest to uncover his origins(maybe FT Team B will do that while this arc progresses). I'm not saying that there can't possibly be more arcs, just that the remainder of the information can be provided rather simply since it is all interconnected. I mean, Zeref's backstory for example. That wasn't just random info, the timing of his revelation was significant and hints at this coming into focus very soon in the present time.
