Speaking of box sets, Outpost Gallifrey just leaked this
First off the number of dvds to be released per year of the classic series will be going up to 10, from 6. That means 11 months there will be Who on dvd, including the new series boxset
2nd, they will now be doing cheaper less extra packed dvds as well as the current extra filled ones. However, they will still be fully restored by the ever great Doctor Who Restortaion Team, and will still have audio commentries, production subtitles and usually a documentry. The cheaper dvds will mainly be for stores that have little or no extras potential.
Finally, some of the releases for later this year (UK dates, US will usually get them a while later)
In October, The Sontaran Experiment, which will be the first of the cheaper less extra packed releases. This finshes of the connected trilogy of "The Ark in Space", this and "Genesis of the Daleks".
In November, The Invasion, which is a classic 2nd Doctor Cybermen story. Interestingly, the 1st and 4th episodes of this story are missing due to the BBCs old policy of dumping old tv episodes, but for the dvd they have been animated (using the original soundtrack and camera directions) by Cosgrove Hall Films (who did the classic cartoon Dangermouse).
Also in November, the new series series 2 boxset will be out, with 14 episodes and a whole load of extras over 6 discs.
And the last of the announced titles is in January, and is a boxset of 3 stories called the "Return of the Master", with 2 Tom Baker stories and a Peter Davison one (which are all connected, and came after each other), the stories are The Keeper of Traken, Logopolis (Tom Baker's last story) and Castrovalva (Peter Davison's first story). Each of these will have the usual RT treatment, with commentaries, productuion subtitles and other extras.
