Love the stats, DadDadDad!
I've said a number of times now I am expecting the entire Tucker family will go, except for Phoebe because she is an Archer by blood. I believe the new Editor wants to prune the cast right back. The number of speaking characters has grown a lot over the last 20 years and I think personally it's too big. There are any number of them we hardly ever hear from - remember how when Caroline and Oliver had a storyline last year there were people posting who'd been listening to TA for a few years and didn't recognise them? They are both core characters from way back, but there has just not been space for all the core people to get a word in in recent years.
People I think will survive as speaking characters:
Archers
Peggy, Christine, Jill - until the actresses die or become too unwell to continue
David and Ruth; Pip if they re-cast; Josh - given that they have just re-cast; Ben (possibly not speaking for a few years)
Kenton, Jolene, Fallon - will Jamie speak again? I rather doubt it, and I live in hope that Kathy has also lost her voice.
Shula - not sure about Alistair - I wouldn't be at all surprised if we were in for a divorce storyline ending in Alistair leaving the village; Daniel will be an occasional visitor, and perhaps will come back to Ambridge in a couple of decades when he leaves the army
Elizabeth, Freddie, Lily - I doubt we will ever hear Lewis again
Pat, Tony, Helen, Henry; Rob - who knows?
Brian, Jennifer, Ruairidh, Adam, Alice, Phoebe - I wonder if we will ever hear Kate again except on fleeting visits; Ian seems to speak all too rarely; Debbie ditto; Chris ditto.
Lilian, Matt - occasional visits from James and Leonie
Token other extended family
Susan, Neil, Emma, Ed, Will, Nic, Clarrie, Eddie (and in due course George, Keira and possibly Jake and Mia)
Others
Lynda, Robert, Jim, Jazzer, Vicar, possibly Usha, Charlie?
It wouldn't particularly surprise me if Oliver and Caroline get a storyline soon designed to mark their official departure from the series. They will sell GG and maybe go to live abroad.
No more Horrobins except for Susan. No more HWMNBN and his family. No more Tom or Kirsty and no more Tuckers.
Mystic Mimsy has spoken!
