Lets see...
Mentioned careers/specialities: Sanctioned Psyker , Techpriest Enginseer, Commissar, Ministorum Priest , and the Guardsman versions: Medic, Sergeant, Heavy Gunner, Stormtroopper . Careers already in DH underlined.
Estimated powerlevel: 20+2d10 stats+ Homeworld (or whatever it will be in this.. regiment or something like the awesome RT origin path?). 25 could be, but it is generally left for heroes, like RT characters or BC humans. I'd guess the exp compared to other systems would be begin at 0 exp, as well.
Seems to me that this is redo of Dark Heresy, with the new rulesystem presented in Black Crusade (although I could guess that ranks are returning in some way). Your opinions? At least I think DH system was feeling quite old already, and refreshing it was needed. But is this the proper way? Create new military-centered core game, instead of DH 2nd ed? Does the 40k line need more combat-heavy lines, so full of official GW material ( I mean, Cadians in Calixis Sector, or whatever the new place will be, might be Jericho Reach or something close).
