Ooooh the suspense!

[I of the Storm]

I suspect it all depends on how many video teasers they have produced. I'm afraid it might be quite a bunch. We had 4 already, Saba, Gauls, Seleucid/Ptolemies and the horse-factions. That leaves Romani, Qart-Hadast, Luso, Sweboz, Casse, Epeiros, KH, Makedon, Getai, Pontos, Hayasdan and Baktria. The release frequency of the previous teasers was 2 days, so it will be 23 days to go until the release of the final teaser, which brings us into November and we all now that nobody releases anything in November since that's too early for christmas presents, so we won't see 1.0 before December 1.
QED.
