I was wondering about this. I just started playing W40K and I'm collecting a Daemonhunters army. I see though the support for this army is very weak. So I asked my local shop if they planned to drop the Daemonhunters just like they killed the Squats and he told me GW was working on a single codex for the entire inquisition, with army lists for the 3 ordos (xenos, malleus & hereticus). Has it been officialy announced or is it pure rumors?
