Q's given us the timeframe that the plan was three years in the making. Given 2017 being the "plan" coming public (to us), three years earlier would fit in with this being the Jan 2015 issue–likely planned out in 2014, of course.
Hmm, just doing some research though I came upon this little nugget: "The magazine is owned by the Rothschild family" and I'm thinking that's a little odd that they would also know these future Q dates…
Trusting the plan and all, having to imagine this is just one of /og/ somehow sneaking it in.
Hard to sneak such a thing by an editor, though; it's pretty obviously there.
