pssst, don't tell ze Zermans but the german release is actually one huge closed beta (get a key buy bying it). Not that D2 hasn't been tested properly before that release... Anyway it just means Larian can rid the International release of bugs, and tweak some features the german owners of the game pointed out improvement.
looking at the german reviews, it's a good game and will only be better once released in the US.
The imho bad thing is that the testing wasn't done more thoroughly.
Who will be happy ? The international market, because they receive a much better games than we did ...
