Yeah...because if a random internet group can scan/translate weekly manga, I'm pretty sure a industry based of it can accomplish it as well. They probably want to but like legit cross mentioned above Japan doesn't let them.
Anyways I'm surprised to hear that Viz only 2-3 weeks behind that's actually real good, I was looking at their site http://www.vizmanga.com/series/5/3 they sell volumes that aren't even out yet for purchase? Or is that online reading?
The site is actually behind the bookstore I go to. For example. my bookstore has up to volume 60 of one piece, but Viz only has up to 59
