It can't be.
There was an article somewhere that the Army had rejected Beretta's proposal out of hand, don't even want to evaluate the updated design.
My guess: The replacement will be the Fabrique Nationale FNS-9 with frame-mounted safety (opposed to the version with no safety). Already a government contractor, the FNS-9 is still 9mmNATO, made in the USA, and has a properly dimensioned Picatinny rail (not a proprietary "accessory rail"). 17+1 capacity, nice small grip for those "smaller statured shooters" who had complaints about the M9.
