yea i would be interested too.
Im from germany too and i never buy anime in a regular store because its never the japanese verson with english subtitles xD its really annoing, if there is german sub why cant they do english ones too? xD
Now that I have watched the first season I have to say that I am kind of disappointed in the subtitles. The first few episodes are alright, but the further you watch the worse it gets. You get the feeling they translated through google. I have to see wether the second and third season are better.
The Publisher is Hong Feng, maybe you find someone else if you want to buy the DVD as well.
I already have Boxes like this from other animes like Skip beat! therefore I know that the subtitles are normally well made (other publishers).
Finally, I have the DVDs of Junjou romantica <3. Let the marathon begin :D
