User blog comment:Silent Psycho Gamer/The difficulties of doing season III/@comment-83566-20130723171705

I think you are overreacting, the vast majority kind of agrees the Third Season will cover only until vol.18 where the magic civil war on UK ends where its the begin of the WWIII.

It would be something like this:

Anglican Church–Russian Orthodox Church Prewar Conference:  1 episode.

Document of Constantine Arc: 4 episodes

Battle Royal arc: 5 episodes

Acqua of the Back arc:  5 episodes

British Royal Family Arc: 9 or 10 episodes

That would make about 25 episodes, of course by making the BRF Arc into 9 episodes would fit the 24 episodes format.

Now even if we cut  1 episode per arc to fit Vol.19 we would be facing serious pacing issues, especially in the Battle Royal arc and BRF arc and even with that 4 episodes for Vol.19(which has far more pages than vol.18) would be way too troublesome given the story is told from about 2 perspectives: Shiage and Accelerator.
