The bad thing is that this 2-disc edition was seemingly exclusive to Amazon here (localized language !) - and that it is sold out.

The only other source of it was a limited edition steelcase version availble from a drug store ("Müller") which also usually has a relatively big media section. I have this version. It's also sold out by now.
I have no idea whether both versions would be available through Ebay Germany, since I haven't been looking for them now that I have at least one of both versions.
In other words : Yes, it's both exclusive and rare. Very rare here, in fact.
This is perhaps different than elsewhere. If something's exclusive, it really isn't produced in that great numbers, usually. It really stays exclusive and rare in a lot of cases.
I sometimes have the impression as if the word "exclusive" has a slightly different meaning elsewhere. I know from Star Wars collecting, for example, that "exclusive" usually means in the U.S. "produced in fairly big numbers for store chains" or something like that. Perhaps the German market really is something different. Even Walmart withdrew from it.
I'm not sure. I can only judge from what I perceive. And even that might be somewhat distorted since all perceivement is subjective.
