There's a few more than 12. Off the top of my head:
Keys of Marinus Android Invasion Face of Evil Nightmare of Eden Horns of Nimon (original Terrance novelisation or Anthoby Read renovelisation) Kinda Warriors of the Deep Attack of the Cybermen [The above 3 ignore the 1990s abridged audiobooks] Silver Nemesis
And possibly . . . Slipback Nightmare Fair Ultimate Evil Mission to Magnus Turlough and the Earthlink Dilemma Harry Sullivan's War
PS When the time comes I hope they do a multi voice reading of The Romans
The Keys of Marinus, The Face of Evil, Nightmare of Eden and The Android Invasion are among those that have just been announced.
