Okay, maybe it's The Secret History with the Fifth Doctor and Vicki, to commemorate both the release of the Fifth Doctor and Turlough and a new story with Vicki?
(If it still hasn't been named, it's up to you, Whovitt. I'm completely out of guesses). :-)
Well, at this point, without any other information, all I have left to suggest are what you and masterdoctor have already posted - The Perpetual Bond, as a First Doctor story with a new companion, and Solitaire, which I'd actually forgotten about as an 8 and Charley story. I highly doubt that a 6-parter would be reduced that much, so I'm discounting The Dark Planet, and I personally think The Bounty of Ceres as a Vicki story and The Secret History as a Fifth Doctor and Vicki story are pretty unlikely, as (particularly Solitaire) has a much stronger link to an October release... except that The Chimes of Midnight has been brought forward to September We should keep in mind that The Chimes of Midnight and Doom Coalition 3 were still October releases when the Listeners title was selected...
The Macros has been a listeners title and it's a six parter, so Dark Planet is a possibility.
So, November has quite a lot of diversity in terms of ranges/eras covered... but I think we can still do okay
To start with, the ranges/eras are: Torchwood, Third Doctor/Jo, Eighth Doctor/Charlie, Survivors, The Avengers - Steed & Mrs Peel, UNIT: The New Series, First Doctor/Vicki/Steven, and Daleks (as Six and Constance are a bit too new for sales).
From here we can do a few quick eliminations (barring exceptional circumstances): 1. Survivors only has box sets and the audiobook; box sets don't get discounted, and it's highly unlikely a 6-disc audiobook will get the £2.99 treatment. 2. The Avengers - Steed & Mrs Peelonly has one other box set; there's the possibility that something from the Lost Episodes sets may get released separately (possibly Tunnel of Fear, although Act 1 has already be released for free in tribute to the original being recently recovered), but it's as likely as Survivors in that respect. 3. UNIT: The New Series is reasonably unlikely, unless it's UNIT: Time Heals, to jog people's memories about the old UNIT series.
Next we have less likely but plausible options: 1. Torchwood is still reasonably new, but there is still the possibility that either The Conspiracy (the first release) or Broken (being Jack AND Ianto, to match the full-cast nature of Outbreak) could be chosen. Of the two, it's far more likely to be The Conspiracy, as it isn't only a couple of months old. 2. Eighth Doctor/Charlie is also reasonably unlikely, as they are the focus of this month's title, however it can't be entirely ruled out. That said, after the slightly left field choice of Other Lives (tell me I'm wrong! ), I will assume it's still a possibility... I just wouldn't have a clue which story to pick
Which leaves us with the 'most likely' choices: 1. Third Doctor/Jo could be a few things: there are the stories barnabaslives has suggested: The Elixir of Doom, Find and Replace, and The Mega, but I'll also put out he possibilities of The Doll of Death, The Many Deaths of Jo Grant, The Scorchies and Ghost in the Machine. They might also pull a trick by making The Mists of Time (from the Companion Chronicles - The Specials box set) available as a download exclusive. 2. First Doctor/Vicki/Steven could be any selection of various Companion Chronicles, but I'm going to go with The Suffering and Upstairs, as both stories feature both actors. Naturally, The Bounty of Ceres is also a prime candidate. 3. Daleks......... well then. I'm going to run with it being a Main Range title, and I'm also going to run with it being a slightly more recent one (though not too recent). For this reason, I'm going to go with either Daleks Among Us or Masters of Earth (it just feels more likely that they'd use a newer release; don't ask me why, 'cause I don't know ).
There then... now I just need to wait for Kenny to tell me I've missed it again, or wait for November to roll around
Torchwood: Probably The Conspiracy. It was part of a Humble Bundle and a year old at this point. Third Doctor Adventures: A Third Doctor CC, probably read by Katy Manning. Doll of Death, Find and Replace, Many Deaths of Jo Grant, The Scorchies, Ghost in the Machine (a spooky story originally released in October) or Elixir of Doom. I was going to suggest Feast of Axos based on the Bernard Holley connection, but that's been done already. Possibly Love and War. Short Trips The Man Who Wasn't There: Unlikely to be the connection, but Time Works or Memory Lane UNIT: Silenced:Mistfall (Jemma Redgrave), Earth Aid (Ingrid Oliver), Industrial Evolution (Warren Brown), The Wrong Doctors, White Ghosts, The Romance of Crime (James Joyce), Voyage to the New World (Ramon Tikaram)
Be sure to check out the indexes for the various Big Finish ranges!
This month's Listeners title is the Companion Chronicle The Beginning. Not sure what the link is apart from it being a First Doctor story like this month's Ravelli Conspiracy. Terry Molloy is in The Avengers Comic Adaptations Vol. 2 though. That could be the link.
