One Piece Volume 0

It seems Oda is in the process of making a "0 volume" in his critically acclaimed series, One Piece. They will be given to those who see the 10th movie in theaters and will take place 20 years prior to the beginning of the story. Apparently, it will tie into the movie somehow, most likely involving the escape of Kinjishi from Impel Down. What's interesting is that possibly makes the movie canon, a first for One Piece movies. You can look forward to both the movie and the 0 volume this holiday (if you live in Japan).
