That's great news for sure!
Regarding the video, it seems a new (old) troop type (that's pariahs) will come alongside Szarekh. I don't think we can elaborate on their loadout because all we can see in the video is that they carry swords which happen to be the only weapon in the video.
The first figures we see besides the Silent King are carrying a sword (the one on the left) and a staff (the one on the right). The figure who's rowing the Silent King's boat carries an almost identical (if not the same) staff so we could think of him/her as a king's servant or council member. Also they have different looking pictograms over their heads so they must be a different "class" (in regards to profession).
The warrior, who is the same height as councilor and the people kneeling before the king, wears no shield, so in addition to that said before we could assume the sword is just an artistic representation of a warrior class. Same goes for the staff but in regards to a ruling/staff class.
