Oda's involvement determines canonicty? I guess this guy, this lady, and this guy are all canon then. By extension, Movie 4, Movie 9, and the One Piece Premiere show 2012 are all canon.

Speaking of Z, what kind of involvement does Oda have anyways? Did he just design the characters and then approve the storyline? That doesn't make something canon.
