this 2-DVD set has:
english and german audio. english and german subtitles (only for restored scenes)
DVD 1 is the uncut version (identical with Anchor Bay) with a serious german dub.
DVD 2 is the cut version (identical with the previous Marketing-DVD) with a funny german dub. no english language for this DVD
the extras look like it's a lot (see link), but actually it's not really much of substance. If you have the Anchor Bay (like me), there's nothing else you really need.
But if you don't, this might be something to buy, but I assume that most of the extras are not english-friendly
