In having the Japanese Blu ray of MII, that was a really good quality version of the OVA. I always felt that it was the definitive version to come. Being that it looks almost like it was done in the past several years (minus the fact that it's all hand drawn), I was thoroughly impressed with that version. I'm excited to see how this goes. So far, I'm quite impressed and I hope this can truly be the definitive version.
I will have to say though, the biggest joy out of this is the Subtitles, but even more is the English dub. I love the original voices, but the English dub is like the best of bad dubbing, and it carries its own epic seal of approval in that sense. I definitely plan to do a watch party when it's out.
