It is not entirely clear on what they plan to do.
Use gfortran via dragonegg?
The 3 DOE labs in the USA have contracted PGI to port
(some of) there Fortran FE to LLVM and open source the
result.

To put this in a (timeline) perspective:
On the 18th of March, 2000, I announced Andy Vaught's work on the g95
front-end to the gcc-patches mailing list.
In 2004 (!) we merged the resulting compiler and run-time library into
the gcc (cvs) repository (obviously, after the tree-ssa infrastructure
went in - 2004-05-17, but before the creation of the 4.0 release branch
- 2005-02-25). Then it took another 2 months for 4.0 to be released.
Unless PGI manages to summon massively large (parallel) working groups
to accomplish this, it might take a few years to fruition.
