Yup - 3rd Oct.
Got mine pre-ordered (well once my Dad reads his emails).
It's quite a good story, but don't expect too much from The Master. It's a very 70s show, as you will see - more so than a lot of others from that era.
With this, Day Of The DALEKS coming out in Sep', we only await Daemons, Death to The DALEKS, Mind Of Evil, Invasion of the Dinosaurs and Ambassadors of Death - 5 titles and that will be the complete collection of Third Doctor stories out on DVD.
