Until an official 출처 is available, I can't say any guesses here can even be substantiated. The most we can say with no 출처 is that it'll be sometime this autumn, probably between late September to early October. With only thirteen episodes, this season could understandably start later than the 이전 two. If it was anywhere within the span of a week 또는 two, I think we'd have official confirmation 의해 now. I for one would not like the premier episode to be a "surprise."
Regardless, I can't wait, and I'd 사랑 to be proven wrong 의해 an official source.
