Well, the question is in the title, who wants to give some first impressions

Got them all. They are good. Buy them.

I don't think you are impartial here

I actually got them, just still had no time to read any of it...

Released Datapulses are:

Berlin
Trollrepublic & Black Forest
Karlsruhe
Austria

Future Release:

SOX

Anything new in them, or do i not need bother, if i have the Berlin and the SOX book?

Of corse they are ma major update, as SOX is ingame and outgame over 10 years old, and Berlin has changed in several ways since Berlin book (but the PDF only works with the Datapuls: ADL).
