In Germany it's out since the last days of February. There's a whole lotta mess out there in the Forums.
As I tried to describe above, there are still bugs and there are features - especially the respawnmnmnmn <img src="/ubbthreads/images/graemlins/delight.gif" alt="" /> - the people aren't very happy about.
The development currently focuses on Multiplayer - there are already some MP Patches out there, but none for SP (although rumors say that these Patches also fix a few things in SP).
Most of the people are indeed talking about MP - and most of them are fans of Blizzards products.
Well, if you could understand at least *a little bit* German, I'd highly recommend browsing throuh the forums there just to get an overview. I cannot pack everything - and especially the overall feeling - of the boards into words.
