I also thought the Chipmixer owner/operator was arrested and awaiting sentence but after looking at the wanted poster via the link, it seems as though he was charged with crimes in absentia. If memory serves correct, servers in Germany were also raided hence the confusion.
We see now that some parts of the EU are still pretty hostile to privacy projects even after the mixer ban, for example
eXch announced it was shutting down because law enforcement was trying to arrest them.
I hate to say this, given that I will benefit greatly from a mixer unban, but a positive reception of crypto mixers in the USA is not enough to cause a ban reversal. There are still many European governments who are fiercely prosecuting mixers and other sites, and nothing is stopping them from targeting Bitcointalk.org either.
