The version of Mein Land that leaked is a very rough demo that was recorded a few years ago. They are also in the process of putting out a music video for it (the re-recorded version) to be put on their best of to be released in November. Also, where did you hear about a 21 date US tour? I haven't heard anything about that anywhere. That seems like a little bit more than they like to do since the band themselves said they don't like doing big tours of the US any more.
