I'll elaborate on what I know. My unit, the 103rd Airlift Wing, Connecticut Air National Guard, was supposed to receive 12-14 C-27Js. When the Pentagon decided to cut the program, we were initially told we would still receive 4-6 airframes.
When the Pentagon canceled the program entirely, we were left without a change to our mission (we currently have C-21As). I have been told by reliable sources, but cannot verify myself, that the one Air Guard unit that did receive four airframes will have to give them back, and that they'll be sold back to the civilian market. Again, this is third-hand info.
As far as the rest of the program, it is absolutely, verifiably, dead.
