The wizards over at GallifreyBase posted their updated spoiler summary for the new season. Among other things: according to set reports and other sources, the newly regenerated Doctor crashes the TARDIS in the garden of the young Amelia Pond, a little girl. He runs up to the house shouting a warning, and later talks to young Amelia. Then he goes back into the TARDIS to do some repairs, and disappears. He reappears a few minutes later - but it's been years for Amelia, now Amy — and she's now a grown-up. She tells the Doctor she had 12 years of therapy. Also, the Earth is threatened by aliens, possibly called the Ataxis, who are searching for the escaped Prisoner 0. They announce via mobile phones and ice cream truck speakers (among other things) that all human life will be incinerated if non-humans don't announce themselves. Prisoner 0 is apparently a dog.

The second episode, co-starring Sophie Okonedo, seems to involve robed men, keys and clocks, and possibly a spaceship. In the third episode, the Dalek one, Winston Churchill's Daleks are called "Ironclads." Episodes four and five feature River Song, who says "Hello sweetie" to the Doctor. And this is probably the "wreck of the Byzantium," which she mentioned to the Doctor previously. River Song reportedly winds up in handcuffs at one point. And there may be two varieties of weeping angels in this story. Steven Moffat told Doctor Who Magazine:

Ahh, you think you know the Weeping Angels ... Well, think again! That lot in "Blink" were just scavengers, survivors hiding out on Earth. What might an Angel achieve at the height of its powers? And do you really think you're safe just because you don't blink...?

In the Silurian story, there are two levels of Silurian society, we may get to see a Silurian Senate, and a female Silurian reportedly falls in love with the Doctor. And the line "Don't diss the sonic!" is spoken. There's a rumor that Rory dies in the Silurian story. And in the just-filmed Stonehenge story, reportedly called "The Pandorica Opens," the Doctor, Amy and River Song visit a museum of history, and some old monsters may turn up. Also, there's speculation the "Pandorica" is like a kind of Pandora's Box, or a piece of technology that River Song finds and activates
