Yes, definitly fillers. It's going to have to be completely unrelated to the storyline though. In my opinion they have four choices.
 * Boss Luffy
 * Chopperman
 * More Mugiwara Theater (there's a lot they could animate).
 * Go back and animate cover stories they skipped over. It would be fun to see CP9 again.
