While on the topic of love in RPGs, I'd have to belive that it won't be appearing much in them, and even if they do feature it it isn't going to be that well developed or engaging (I have not played Dragon Age: Origins, so I wouldn't know anything about the level of NPC interaction in the game) because there is not really much of a demand for it. Right now gamers want to see more blood splatter than romantic chemistry in gameplay.
And to address the rest of the large white box hovering over my typed characters: combat is moving away from turn-based fighting.....unless you include FF games which will never truly abandon it's turn-based roots. Moral decisions are an area that I'd rather not get into because while they seem interesting, I'd rather not think about whether I should shoot the random dog or give him a treat (Dogmeat has alot of health)
It's there in DA:O, and it does open up a few more doors than just selecting what "sexy cutscene" you'll see, but it's still not a very full implementation. It is, however, done better and more thoroughly than anything else I can recall playing recently. You're probably right though in saying it's probably pretty low on the priority list of most devs... which is a shame seeing all of the doors it could open.
