The biblatex
approach to bibliographies is very different from that used by 'traditional' BibTeX, which includes natbib
. The way that a traditional style works is that BibTeX-the-program reads the .aux
file (for citations), .bib
file (for data) and .bst
file (for style), and write a .bbl
file containing the formatted output. The latter is then typeset directly in LaTeX (i.e. \bibliography
is a special form of \input
). When using biblatex
, in contrast, citation data (from the .aux
or .bcf
) is used along with the .bib
file to give a database-like .bbl
file. The latter is used by biblatex
to do formatting at the LaTeX end (i.e. in LaTeX macros). In this cases, formatting is driven by a .bbx
file, which tells LaTeX (not BibTeX) how to do the style. The two approaches are thus fundamentally different.
It is possible to write a .bbx
file which does the same as any given .bst
. Thus as well as the standard biblatex
styles, there are styles available which match the BibTeX 'traditional' set. There are also implementations for some journal styles. Included in those is biblatex-phys
, which implements the AIP and APS styles. As those can never be used with natbib
, and thus not with REVTeX, they are not official and cannot be used to substitute in journal submission. (See Is biblatex compatible with RevTeX?.) (Note that one can 'unload' natbib
as discussed in Is it possible to load biblatex with a class that has already loaded natbib?, but this would be a bad idea in any official submission.)

and the question should be: Is RevTeX still using natbib instead of the betterbiblatex
?
