This may have no baring on anything, however in 2003 DW magazine (issue 332) did a poll of the top 40 stories people wanted to see on dvd. Since then 7 of the top 8 choices have been released- or are about to be- which
may suggest the poll had some influence on the release timetable. The ones on the poll yet to be released, in order of the fans preference to see them, were:
1. The Seeds of Doom
2. Logopolis
3. The Daemons
4. The Deadly Assassin
5. The Sea Devils
6. The War Games
7. The Time Warrior
8. The Trial of a TimeLord
9. Day of the Daleks
10. Terror of the Autons
11. Planet of the Spiders
12. Terror of the Zygons
13. The Brain of Morbius
14. The Masque of Mandragora
15. Kinda
16. Robot
17. The Chase
18. Castrovalva
19. The War Machines
20. The Horns of Nimon
21. Survival
22. Mawdryn Undead
But who can say. I doubt we will get another William Hartnell for a while, seeing as we've just had 4 of his in quick succession. And yes, there are people like me who really do like Nimon. Sorry if you can't understand. Well actually, I'm not.
