Do you mean in a contributed package to be installed in R?  There are no 
plans to use F95 in R itself.

If so, perhaps by 2.3.0, but there are a lot of issues to resolve.  For 
example, how do you indicate that the source file is F95?  Some compilers 
accept a .f95 extension, but not all (and it is not ever clean which do).

It is not. The largest R platform, Windows, does not have a supported F95 
compiler.  (g95 works with MinGW, but R has no support for it as yet, nor 
can one expect people to have installed it.)

Why do you think gfortran is a F95 compiler? (It has considerable support 
for F95, but not complete support AFAICS.)  And that it is the only F95 
compiler?   How do you propose to tell if you have a F95 compiler?
