@Aizen sorrow

What I meant there was that the story was meant to be split into 3 parts, and if Kubo (not saying he does) considers everyting before the Arrancar arrive as one entire arc (The Substite, Entry and Rescue arcs up until after they return from the Soul Society), and then everything after that point up until the end of these Decide chapters as one arc, then the final arc would most likely be broken up into smaller arcs but ultimately defined by him as "one arc".

Anyways, the thing I was getting at is that if he did consider everything up until now to be two Arcs, one being the about Shinigami and the other being about Arrancar, then the Final Arc MAY be about something completely different (such as enemies from Hell or people from the Royal Guard).
