Random House took over the audio distribution but don't seem to have any interest in creating original material. Hell, there's at least one original 11th Doctor audio that was recorded in the Audiogo days that they haven't bothered releasing and Paul Magrs has written another series of his 4th Doctor stories that doesn't look like ever being made.
The one upshot is I can see Big Finish finally getting the New Series rights once their license is renewed. (Sadly their current one goes to the end of 2016 so it's a loooong way away yet.)
