@sensui:
I think you're confused a bit. These log collections are DVD releases of the series that's ongoing right now and each of them have a character in the front it features (usually has to do with the arc the episodes are about I think). Need to stop these nonsense releases and get to the BD already, the high def broadcasts are better quality than these releases. But thanks for the pics Eneru, I always wanted to see what was included in these releases.
You're not quite right.
Log Collections are DVD boxes they release just to milk money. It's not "ongoing series", it's re-run of first eps.
Regular anime DVDs are only up to Sabaody Island.
These is just a re-release of same old crappy DVD quality in fancy boxes with additional merch.
Each includes about 20 anime episodes.
They did episodes 1-131 so far with 8 Logs.
Logs were East Blue (Luffy cover), Sanji (Sanji cover), Nami (Nami Cover), Logue Town (Zoro cover), Grand Line (Usopp cover), Chopper (Chopper cover), Arabasta (Ace cover) and Vivi (Vivi cover).
Each set has different extras (like first box only had booklets, I belive Vivi one had the most extras so far).
Covers they used were Oda's Excellent Scene drawings for Manga Logs so far, expect for Ace, which is anime-drawing, stylised.
I don't think they announced more of these logs after Vivi yet.
