Well for all Viz's mistakes, they're still better than most of the other volumes around the world from what I've heard. Not like the German volumes haven't changed names or done edits. Plus the German volumes have such terribly ugly covers with the dark orange title and dark blue background.
Plus I think a lot of countries miss out on SBS entirely.
Overall Viz is putting out a pretty good product well worth the cost.
I'm not going to discredit the fan complaining though. While I'm not nitpicky enough myself to do so, it was the nitpicking of very vocal fans that may be responsible for our largely unedited (when compared to Naruto volumes) speed-up.
I mean, honestly One Piece's fanbase here isn't nearly as large as Naruto, or even Bleach. They could've chosen to do a Bleach speed-up promotion instead. They could have let One Piece continue crawling at it's incredibly slow pace and we could be getting volume 53 in June 2020…but they gave us a speed-up and it was largely done for those very vocal fans of OP. I did send a few e-mails asking for a speed-up as I'm sure very many of us here have....but only one about some of the mistakes. I think we have to thank those who complained more vocally for the lack of edits we've seen since Skypiea. I think the lack of 4kids influence past this point also plays a role.
Some things like Zolo were out of Viz's control. Up through Skypiea, there are terms and names that 4kids had influence over. It's very possible Shueshia or Toei or whatever company was the cause of Zolo for Viz may have pressured Viz to match up the manga with the anime and terms used in games like Grand Adventure.
Of course past this point, there is no more 4kids influence, so perhaps that is why we don't have to deal with things lik "Kami" anymore.
It's obvious they're fine with references to God in Impel Down / Marineford...
I still think the speed-up was originally being planned for only Skypiea and thus Skypiea was done possibly much earlier...and with the few products like Grand Adventure out there with 4kids influence, Skypiea had standards more in line with Viz's other series like Naruto.
Regardless, we at least have a pretty much unedited translation from this point forward....and honestly I don't think OP is at the half-way point quite yet, so we've got a lot more volumes to go!
