Is Greencapt doing anything at all with the ORIGINAL Japanese audio? I'm not a very big fan of dubbing at all so I hope he does a dual release with the actual Japanese language. In my opinion, it'd be more of a truer preservation if he didn't mostly focus on the dubbed version and paid a bit more attention to the aforementioned Japanese audio.
All that aside, I'd much rather own a Japanese audio minus the dubbed version with alot of the extra features. Hell, I've never even listened to the dub, only the original Japanese language version so I've no idea how both the old and the new dub sounds.
Oh, and the manga is loads better mainly because if the movie had kept in alot of things from it, it'd be over 4 hours long probably. I think...
