well, I don't know them, but if they write something like that it makes me believe that they did a good enough job.Joint with THORA, translated (from scratch) by yours truly. I actually had the script done the day the BD came out, but there’s a lot to work that goes into subbing a two hour long movie, especially if it’s quality subs we’re talking about.
I'm not going to download it yet though, the blu-ray release here in germany is just 2 month away (I've waited for over a year... I can wait for a little longer) and support them a bit by buying it ^^. (official dub releases just ~2 month after its release in japan is really good and worth supporting if you ask me... even though I won't even listen to the german dub.. ha)
