The boring answer is:
Clara will die in episode 10,

But stay tuned ... for the most brilliant fanbait theory ever!
(warning: no spoilertagging from here on)
The BBC have published
the following photograph:
It's a tribute to the Beatles, referencing the following photo from 1969:
First off, let's just confirm:
This is a very carefully done reference.
Both photographs are taken at the same crossing on Abbey Road, with a white VW Beetle as the first visible vehicle on the left side of the road and a black taxi cab as the first one on the right. The Doctor is smartly dressed like John Lennon and imitating Lennon's pose and gait. Clara is barefoot like Paul McCartney and pointing her finger to imitate McCartney's cigarette. There's no denying the clarity of the parallels and the care that must have been taken in staging this photo.
Now on to the conspiracy theory!
The Beatles picture has been famously used as evidence for 'Paul is Dead'.
There is a well-known conspiracy theory 'Paul is Dead', which asserts that Paul McCartney actually died in a car crash in 1966 and was replaced by a body double for Beatles appearances thereafter. This photo, from the cover of the Abbey Road album, was used as evidence for the theory:
The cover, which shows a photograph of the Beatles walking in step across the street away from Abbey Road Studios, resembles a funeral procession. Leading the procession is John wearing white, symbolizing the clergy. Ringo, dressed in black, is a pallbearer or an the undertaker. George, dressed in work clothes, is the gravedigger. Paul, the corpse, is out of step with the other Beatles, leading with his right foot instead of with his left. Also, Paul’s eyes are closed and he is barefoot. Asserting that because people in many areas of the world are buried barefoot, Paul McCartney Dead: The Great Hoax stated that this was “a strong death symbol.” Also, Paul is smoking a cigarette, also known as a “coffin nail“. He is holding the cigarette in his right hand, even though the real Paul McCartney was left handed.
Behind the Beatles on the left side of the street is a Volkswagen Beetle with a license plate reading “28IF”, suggesting the Paul would have been 28 if he were still alive. Actually Paul would have been 27 when Abbey Road was released. For those who thought that this was just too tantalizing to let pass, Paul Is Dead: The Great Hoax explained, “To the believer, 28 IF does symbolically state Paul’s age—since people (especially in the Near East where Paul learned mysticism) believe we are all one year old at birth (counting the nine months of pregnancy). True, in this light, Paul would have been 28 IF he had lived!.” The first three letters on the license place, “LMW,” has been interpreted as “Linda McCartney Weeps”.
OK, OK, this seems pretty crazy. But regardless of whether or not you believe this theory, there's no doubt it exists as a theory. And the Doctor Who team must have known about this, because...
The parallel to 'Paul is Dead' is 'Clara is Dead'!
I've already mentioned the parallels between the Doctor's garb and John Lennon's, and between Clara's bare feet and finger and Paul McCartney's bare feet and cigarette. That's not much on its own, but let's take a close look at that Beetle reg:
Jenna Coleman (born 27 April 1986) is 29, and so will Clara Oswald (born 23 November 1986) be by the time Series 9 finishes later on this year. So it looks as though Clara will die in one of the episodes due to air before 23 November, so that she would on that date be 29 IF she had lived! And DWW, interpreted like LMW in the original, obviously means "Doctor Who Weeps".
Surely all this evidence, the number plates included, is far too much for coincidence. The suggestion is clearly that Clara will die in or before episode 10 (airdate 21 November) of series 9. This must be one of the cleverest pieces of fanbait ever made!
