From the top 3….well I like Naruto XD.
11th isn't bad for only volumes 56 and 57 being released in Q1 and Q2. I mean....volume 50 of Naruto came out when 56 of OP came out and volume 51 of Naruto came out when 57 of One Piece came out, but we already know Naruto outsells OP by a wide margin in the US unfortunately.
Death Note is probably so high because they're reprinting it in bigger double volumes. I think four double volumes (1-8 in the original volumes) came out this year alone so far. I mean, I know Death Note is popular but otherwise it would be very difficult for a 12 volume series that ended 3 years ago stay so high in the sales......though Dragon Ball still somehow sells a lot.
They're doing omnibus releases of Naruto, Bleach, and FMA as well so that likely boosted sales for those series.
Next year it might look a little different. The reprint of Death Note will be finished by then and so will Fullmetal Alchemist.
Now, don't get me wrong, I think Bakuman is great, but it's good to see One Piece did better. Bakuman had volumes 3, 4, and 5 released in Q1 / Q2 since it switched over to a bimonthly release schedule. Bakuman is one of Viz's better selling titles and had three volumes out, but OP did better which is a good sign. It's definitely holding it's own after the speed up.
