Amazon.de has changed the languajes of season 3 now only have Germán.
The discs will also include English audio but yes: according to information from other german dealers the originally announced italian, french and spanisch audio isn't included for this blu-ray release of season 3 anymore.
So this season 3 release and the comming season 4 release both will include english and german audio only. A bit strange to forget about at least the french and spanish speaking fans as they are also relevant in North America and not just Europe. But making sense of Paramounts/CBS' international distribution of physical media has become a hopeless undertaking in the last couple of years.
