There has not been any official details that I know of, but I'd expect this release to be in English and possibly French.
It is a North American Xbox release, so will most likely be NTSC only. Since Germany uses PAL for TV video, it will probably not be compatible with a German Xbox console. Publishers can choose to release region free DVDs, but earlier releases of D2:ED and DKS were not. Since this is the last release, it is possible it could be region free, but you would have to check with the publisher.
