Hope you guys don`t forget?
KISHI himself is writing the story for this filler arc, whice(as i know) he never has done before. How knows. Maybe it will get interesting
My guess is that they will try to show of all the tails in the anime, so like we got to see a flashback on how Deidara joined Akatsuki in the Anime(and Manga?), we will probobly see some kind of flashback on how Itachi caught the 5 tail(like we got to see Kisame holding the 4th tail on his sword) and how Kakuzu caught the 7 tail(or maybe it was the other way around?) when Madara and Zetsu and/or Kisame are having an conversation about their goal and/or the past members, etc
