Yeah, probably...
Also, this is one source only, and I've not seen this news anywhere else (not that I spent much time searching however).
Tail section located is, however, good.
Hope everything aft of the rear pressure bulkhead is still there and still intact...
Edit: the source quoted in the article is ANSA, and here
Brasile: incidente Air France; ritrovate le scatole nere - Trentino-Alto Adige/Suedtirol - ANSA.it
and here
Airbus Air France,trovate scatole nere - Top News - ANSA.it
(which I got as google.it hits since I found nothing on google.com)
there still is mention of black boxes...
Time will tell.
