I listened to the NTSB briefings. That is official enough for me.
I'm sure Google/YouTube is your friend too!
Heck - I think they even put out info on Twitter -can you imagine that!?!

I don't know when the autopilot was disconnected do you? We do have an author quoting an ntsb official saying the autopilot was on until the tape stopped recording. We also have many quotes of the autopilot was on until just before impact. 7 seconds could be just before impact in my book. I don't know Ill wait and see.
media briefing on UPS flight 1354 crash
in Birmingham, Alabama, August 16, 2013
Discussing the Cockpit Voice Recorder:
2:52 - NTSB Member Robert Sumwalt: "16 seconds before the end of the recording was the first of 2 audible warnings, audible alerts that are generated by a computer known as Ground Proximity Warning System. This alert anunciated, 'Sink Rate, Sink Rate.'"
3:22 - NTSB Member Robert Sumwalt: "13 seconds prior to the end of the recording, one crewmember reported to the other that the runway was in sight.
3:36 - NTSB Member Robert Sumwalt: "9 seconds prior to the end of the recording we have sounds that are consistent with impact."

Discussing the Flight Data Recorder:
1:42 - NTSB Member Robert Sumwalt: "The autopilot was engaged until the last second of recorded data."
(Discusssion of the difference between CVR and FDR recorded data. The FDR ended before the CVR, so the "end of recorded data" for each is different.)
2:54 - NTSB Member Robert Sumwalt: "The autothrottle was engaged through the end of recorded data. The recorded airspeed was tracking tracking the autoflight selected airspeed of about 140 knots, which is consistent with the expected approach speed."

So there has been nothing new from the NTSB since Aug 17th. We do have the Wall street journal article that appears to contain new information and this statement:
"The autopilot remained on until the last few seconds before the jet clipped a power line, hit some trees and erupted in a fireball."

I'm a full-service contributor. 
(Wait, somebody's gonna take that wrong.

I don't believe that's new information -- it simply describes the "sounds that are consistent with impact." We've seen pictures of a clipped power line and trees that were damaged, and, of course, we've been told about a fireball.
What strikes me is the voice 4 seconds prior to impact, "Runway in sight." That sounds like they thought everything was going just fine, looked A-Okay, right up until seconds before it clearly was not.
What I've learned by studying the GPWS Mode 1 graph is that if I ever hear "Sink Rate" a half mile from the runway, it AIN'T just fine, it AIN'T A-Okay. It doesn't matter if I can see the runway at that point. What matters is can I see the ground? So, it doesn't trigger a GPWS escape manuever in our airplane book, but it sure as heck triggers one in MY book from now on.
