Some have touched on the subject of death animations/ragdolls, and I think that is a very good point. RO1 has some very impressive rag-dolls, but what would be really cool (and impossible at this point) would be to use the Europhia animation software. If you have played GTAIV or Red Dead Redemption you have seen this at work. It will generate, in real-time, animations based on external forces (physics). For example, when Nico is drunk his stagger is a predetermined variable, but tripping over things, or loosing control of his inertia is all physics based. The engine creates animations based on you tripping over the sidewalk, and things like that look very natural and "un-canned".
From some of the videos released the rag-dolls look similar to RO1's, but again that was all very early footage and it looked like some glossing over was to be done.
