I just want to let you know what a German friend of mine told me.
You can get HP 6 on German Amazon before it is available on our Amazon. Here is an easy description how to orderhttp://www.how2orderdvdandbdatgerman
And the coolest thing ever is the "castle edition" is available as well, I already dispatched my order for it. I haven't seen this here so far.
I hope I could help you.
