Just when you thought you were truely done with them it seems like a filler saga will now be placed in the anime. Here's what leafninja said:
With the airing of Shippuuden episode 54, the series featured a new opening which revealed 5 new filler characters. Episode 54 ended with the start of this new filler arc. Before one has an aneurism, note that we don’t know how long this filler will last or how involved it will be. It appears some portion of the canon material will continue in the episodes. It could be 7-8 episodes or a lot longer. Originally in the manga, there was a period here where it was a natural fit for filler. So it’s no surprise Studio Pierrot is using this opportunity. It’s also unclear what this filler will exactly deal with, however, manga only readers will know that certain events transpire which could be addressed in the filler to answer issues about an unknown Jinchuuriki (See Unknown Jinchuuriki Three in our Jinchuuriki Guide if you don’t mind the spoilers) or highlight a certain character before he disappears from the series. Whether the arc will feature these two things is unclear, here’s hoping for the best though. Also, the filler portions may be about something else entirely and not a Jinchuuriki, so don’t get your hopes up.
If you watched the opening then you saw the characters that leafninja was talking about. If I believe Master2005 posted it in this section, cool opening and all, but seriously, don't they think we've been through enough filler hell?
