No, I clearly mentioned that there wasn't any issue with the Japanese voice cast either. The Japanese voice for Crowler just said that GX wouldn't be renewed for the spring a couple of years ago. It had nothing to his role on the show or any of the cast members. The reason why they didn't continue GX through the spring season of 2008 was because they wanted to go into 5D's sooner and the ratings might have been a factor as well. I don't know why you thought I said something differently, but I apologize in case it wasn't clear enough. I'm also confused as to why you thought it was going to be renewed in Japan. GX ended its run in Japan back in 2008. I don't know if they even air reruns on a channel there, but even if they did, they wouldn't renew it. They're focused on finishing up 5D's and then airing the new Yu-Gi-Oh! Zexal series. Unless they decide to go back and remake the GX anime, they won't renew the series. Being renewed also doesn't mean that that it will have to air in the U.S. in a certain amount of time, especially if 4Kids can't afford to dub the series.
Wikipedia is not a reliable source of information since anyone can edit the articles there. 4Kids releasing a press release statement or discussing this issue in an interview would be a much more reliable source for your claims. As for the DVD question, I'm afraid that it is too much to ask 4Kids to ask something like uncut DVDs. Like mumbo mentioned, they don't have their own DVD distribution line and after Funimation stopped being the distributor, it would be kind of hard to find an outside company to release DVD's again. Not to mention that there actually are legal issues with releasing uncut Yu-Gi-Oh! DM due to the Japanese voice actor for Yugi, Shunsuke Kazama contract expiring. It prevented them from putting up the raw episodes on their YouTube account and those old uncut DVD's, both of which were confirmed by that interview with ANN last year. I'd love to have all of the Yu-Gi-Oh! series on DVD too, even if it was just the dubs, since I enjoy all of them too, but unfortunately, it won't be happening anytime soon due to their financial state.
