@Samwize78:
Even if we get Season 4 DVD's, they might still be in 4:3 since the Japanese DVD's of the corresponding episodes were in 4:3 as well, so to my knowledge there are no 16:9 One Piece DVD's in any country (correct me if I'm wrong anyone), unless Toei can give FUNi the widescreen masters for those episodes. Here's hopin'!
The series was released 4:3 in Japan up through the end of the Davy back Fight, and the filler arc right after. Starting with 229 (Japanese Season 8) the series was released in two formats, Widescreen 16:9 DVD for purchase, and a 4:3 cropped release you could rent (For consistency's sake I suppose)
If you ever find any cropped 4:3 DVD raws of episodes from then on, they came from rental copies. And let's face it, anyone who is going to bootleg the series isn't going to actually buy it if they can just rent it…
Also, according to Amazon.co.jp, the Log containing the Foxy and Filler Episodes will also be 4:3… In fact, it says the next two volumes (Water 7, and the "Rocketman" Set) will be in Fullscreen too... what the hell?...
B... But, the single DVDs were 16:9…. What?!
