BBC has released more information about some forthcoming DOCTOR WHO Season/Series 7 episodes.  Specifically:  a few more titles, and a better sense of their pedigree.  

We recently learned that episode one of S7 will be entitled Asylum of the Daleks.  We now know that the second installment of this Season/Series is, quite magnificently and most promisingly, called Dinosaurs on a Spaceship -  written by Chris Chibnall (who scripted S5's Silurian-centric The Hungry Earth and Cold Blood) - about which current DW overboss Steven Moffat indicated: 

The Doctor will come face to face with some of the most monstrous creatures evolution has ever produced, on some of the most monstrous sets we've ever built.

The third S7 episode is called A Town Called Mercy, and guest stars FARSCAPE's Ben Browder.  It's scripted by Toby Whithouse (S5's The Vampires of Venice and S6's The God Complex (Docback HERE, see it HERE).  This is the show we saw some material from in the first Season/Series 7 promo a while back (HERE).  

Both Dinosaurs and Town are directed by Saul Metzstein, an accomplished television director with titles like the recent UPSTAIRS DOWNSTAIRS to his credit.  Metzstein also served as Second Unit Director on the upcoming Karl Urban-starring JUDGE DREDD adaptation, DREDD.  

A few more details can be gleaned via a BBC release on the mater, HERE.

The DOCTOR WHO News Page also indicates that the title of S7, E4 was announced at San Diego Comic-Con over the weekend.  It's evidently called Cubed.
