That would be pretty nice, even though I would always watch the English version since I do that with all of the bilingual DVD sets I have.
I loved Monster Rancher. That was one of my favorite shows to watch back in the day on FOX/ABC Family. I would be happy if the series was released on DVD with just the dub, but that's me.
I also favor in the CardCaptor Sakura sets. I believe Amazon and other online stores still have the sets or the singles, but it would be still awesome if it could be released again so more people had a chance to get it.
I'm also in favor of the Digimon re-releases. I wouldn't mind if it was just the English versions for the other four series, as with the case with Data Squad, but I remeraber liking those dubs. Some of the dialgoue was odd, but not that bad as I recall.
I would love it if VIZ had sets for Zatch Bell, Hikaru No Go and Megaman Starforce since it's really hard to find the single discs for these series nowadays, especially Hikaru No Go.
If U.S. seasons count, I would love it if Pokemon Johto Journies and Johto League Champions could be re-released as box sets. They could also do the same with Master Quest so that the whole Johto saga could be available on DVD. I haven't seen the first two Johto seasons in years and it would be nice to see them again. I think that Johto League Champions was released on DVD, but those are out of print, just like the videos for Johto Journies. Since Heart Gold and Soul Silver are on the way, it would be really awesome if PUSA could release those seasons in order to promote the remakes. That would make me happy.
