As Promised here is the episode teasers direct from Russell T Davies in this weeks Radio Times. I've edited the first few episodes down a bit to save my aching back and burning typing fingers, but the gist of the entry is intact.
As always RTD's style is somewhat informal and somewhat conversational. Anyway, here they are, from the pen of RTD.
1
Partners in Crime
Modern-day London, and a brand new diet-pill is being tested by Adipose Industries. Slogan: "The fat just walks away". But soon there are unexplained deaths, strange creatures in the shadows, and the Doctor starts investigating, little knowing than an old friend of his is also on the trail…
[On Catherine Tate as Donna in general] But thank God we decided to risk it and actually asked. And Catherine said yes! Immediately! And her performance is just dazzling. After Rose plucked at our heartstrings, and Martha's love went unrequited, it's wonderful to have a companion who isn't interested in the Doctor that way – she's a friend, an equal and a conscience, and I swear she will break your heart.

The Fires of Pompeii
Pompeii AD 79 and its volcano day!* But there's far more than Versuvius to worry about: psychic powers are running rampant; a secretive Sisterhood conceals a horrifying High Priestess; and beneath the ground, vast creatures are stirring. This is where Donna truly comes into her own challenging the Time Lord like no-one's ever done before, with one vital question: If he knows everyone is going to die, why can't he save them?
3
Planet of the Ood
Donna's first visit to an alien world. And it's freezing! But on the icescapes of a distant planet, the greatest danger might be from the human race itself. When the Doctor meets the Ood again he's determined to find out the truth behind their servility. But when an Ood's eyes turn red, you know you're in trouble, and the red-eye is spreading…
4
The Sontaran Stratagem
5
The Poison Sky
The return of Martha Jones! We've seen Freema Agyeman take Martha from Doctor Who to Torchwood, and now back home again in her new job as medical officer for UNIT, a worldwide army dedicated to fighting alien menaces. But the menace is bigger than ever, as the threat of ATMOS spreads across the planet. Sounds as if she needs her old friend, the Doctor. But he's about to meet an old enemy, as the Sontarans lie in wait – the warlike, potato-faced monsters not seen on screens since 1985. They're back, they're brutal and they're out for revenge.
6
The Doctor's Daughter
Yes, that's the title! And it does what it says on the tin. I'm saying no more; just watch David Tennant take the Doctor into new territory , with his most splendid performance yet.
7
The Unicorn and the Wasp
In 1926 Agatha Christie mysteriously disappeared, only to be found 10 days later, with no memory of what had happened. Was it a nervous breakdown? A cry for help? Or perhaps a giant alien wasp?
It's a classic murder mystery, with a country house, vintage cars, a flapper, a vicar, a butler, a body in the library, tea on the lawn, and horrible deaths. And see if you can spot how many titles of Agatha Christie novels are hidden in the dialogue.

Silence in the Labrary
9
River's Run
Just to warn you Stephen Moffat created the "Are you my mummy?" Empty Child, Madame de Pompadour's Clockwork Droids and last year's Weeping Angels ("Don't Blink!"). But I think he was just warming up, getting ready for this year's adventure. Now we've got two episodes of terror in an abandoned library, moving shadows, the gruesome Nodes and the horrifying Data Ghost – possibly the most spine chilling scene I've ever seen anywhere. Don't blink indeed. Don't miss a second.
10
Midnight
The planet Midnight: a giant leisure world! Golden spas, diamond landscapes, anti-gravity restaurants… what could possibly go wrong? But for once the Doctor is left powerless and terrified as the knocking on the wall begins…
11
Turn Left
The strands of Donna's story being to draw towards a terrible climax as she finds her life, her family… her entire world being devastated. Only one person can help. But this time it's not the Doctor – but someone from a parallel universe, a woman thought to be lost forever…
12
Title Withheld
13
Journey's End
It's the big finale and the title to episode 12 is being kept secret as it gives away too much. But the threat is on a truly epic scale, as an ancient enemy is resurrected, and a whole universe is thrown into danger.
Who are the Children of Time? What is the secret of the Vault? And surely, not everyone can get out alive…?
* Do I get bonus points for spotting the Captain Jack reference?
