This is good news indeed. I was really hoping to hear these news soon rather then later, and them saying it will be better then Strong World sounds good I suppose. Now the question I'm mostly thinking about is who's going to be the animation director/character designer of the 12th movie. 7 and 8 had Eisaku Inoue, 9 had Naoki Tate and 10 had Masayuki Sato. And I don't count 11 since it's the 3D one. I'm also going to assume this won't be a 3D movie.
On a side note, I have only seen likem the first half hour of Strong World but from what I know it looked pretty good so I wouldn't mind Masayuki Sato being the animation director. Noboru Koizumi, who did movie 5 and those might also be nice choice. Basiacally any of the people I mention has the potential for making the movie look good.
I would really like to see either Noboru Koizumi or Kazuya Hisada take a stab at it, but hey I don't mind any of the other guys so yeah. But I'm mostly just hoping for a good nice looking kick-ass One Piece movie set in the New World.
