No, it's not up for pre-order yet. There seems to be a delay which Cubicle 7 have said is down to a hitch with the paperwork, so the advance pdf copies still haven't been sent out to subscribers.
As for the 7th Doctor cover competition, I figured that with the 6th Doctor book delayed, the 7th might follow it fairly quickly. So I went ahead to give people time to post their guesses.
Incidentally - not participating? Is a ticket to the Psychic Circus not an attractive enough prize? How about if I throw in a pair of spoons so you can stay alive keep the audience entertained a little while longer?
