Yes, in Japan and in most of the anime/manga communities in America.
But here, in America, One Piece isn't a high seller like Bleach or Naruto.
Viz Media including One Piece to their "The Big Three", when there's a big difference in popularity in the States, just seems inaccurate.
That may be true but I would rather have One Piece still promoted as much more popular than it actually is than the opposite.
In other news, I got the newest SJ and I am a bit dissapointed that while Naruto got color pages in this issue Viz dropped the ball by not using the color pages for the "New World" chapters as well as taking out the nice color spread. Viz has usually been good with One Piece on that sort of thing (like the whole Cross Epoch, and publishing Romance Dawn stuff).
