"Did it release less volumes this year?"

Yep. Oda is taking huge breaks on the way.

"Really trying not to rag on One Piece but 2010-11's numbers compared to the last two years is an extremely deep decline [1]! Not trying to cause panic, but if the decline continues at its current rate One Piece (and jump itself) could be in real trouble."

You think so? I doubt it. OP has been Jumps golden boy for years. And by the looks of it; Jump has no intention of stopping it. And if you look closely, lately, OP has been only used for advertising and commercial purposes. And I don't believe jump would decline it. Since it reached 300 million in total volume sales a few days ago.

But if Oda decides to stop it, well that's something else.
