Eh, you are battling demons, you are going to have an inventory system where you collect tons of junk, and you get to play online ala battlenet. It doesn't sound very Doomish to me, it sounds like a futuristic version of Diablo. Also, the more gameplay footage I see, the less it looks like a regular point and shoot FPS game and the more it looks like it's skill and stat based. Of course I could be wrong, I've barely followed it at all, just read snippets here and there and a few videos.
Oh, the cut scenes are pretty epic, and that was really the best part of Diablo anyways.
