The Flight Data Recorder has been recovered.
EU Agency for Aviation Safety chairman Pekka Henttu claims to be close to the investigation into the Germanwing's crash, and to have unofficial information as to the contents of the cockpit voice recording. He suggests the crew may have been unconscious contrary to official reports, but believes there is no reason to speculate.
Henttu told Finnish news Yle, "Sound recordings indicate that the pilots have apparently been unconscious," and added that the descent was arrested a couple of times.
Meanwhile, the Bureau d'EnquĂȘtes et d'Analyses (BEA) who is heading the investigation, states during a press briefing today, that while the cockpit voice recorder has been found and an audio file has been sucessfully extracted from the device, that no specific information can be determined at this time. The briefing also reported that no portion of the Flight Data Recorder (FDR) has been found, contrary to what the media has reported that the FDR has been found but extensive damage has prevented investigators from accessing the data.
EDIT: And it appears that the copilot locked the pilot out of the cabin when the pilot went to the lavatory. Either that, or maybe the copilot passed out and the cabin door locked automatically when the pilot went to the bathroom. The audio recording showed pounding on the door but no response from inside the cockpit.
