Though maybe he will this time. Six months of people going, "Who was John Hurt playing?" wouldn't necessarily be a bad thing.
I don't know, everyone has already figured it out, and John Hurt himself kind of admitted it in an interview. The smart thing for Moffat would be to confirm it anytime now, to avoid the kind of mistake Abrams made keeping Benedict Cumberbatch's role in STID a secret for so long. Now that that it is confirmed who his character is, everyone's attitude is "well duh, why was it kept a secret for so long?" Lesson learned, secrecy doesn't build hype, it kills it.
