I couldn't help being slightly amused by the story in today's Sunday times (back page, Section 1); it lists the various options, but gives diagrams of the runway proposals. For Cliffe, off the Kent coast, they have two parallel runways (OK, fine), then two more in a kind of "crossed swords" pattern - no obvious room for terminals. (One would assume any new runway would have parallel runways a la Atlanta/DFW/CDG).
For LHR, they have an extension to 23/05 and the new runway, north of 27R, running from the "new" threshold of 23. Obviously, they're into guesswork. Still, the editorial and the story itself is very positive.
R3 at LHR seems to be very much in the running . . .
