Okay, I'm giving this a high rating because I am thankful that these box sets are as close to the original as we can get. But I do wonder:Why we can watch the American dub with Japanese music on the blu-ray movies, but no original Japanese voices with the American music? I've gotten used to the original Japanese music but I would be really pleased if we could have the original voices with subtitles and the American tracks. That would be awesome and I think a ton of people agree.Also, I've read that the original Japanese Dragon Boxes (either box 1 or box 2) had additional stuff, like the OVA 'The plan to destory the Sayijns' and I see no evidence that the American Dragon Boxes are going to contain that.Can anyone clear this up for me? Also, do we think these will ever be released in a blu-ray format?
