Bioware *was* top tier when it came to writing, but they haven't written anything good in over a decade. Pretty sure none of the writers for earlier DA's are still around (or at least not many). Maybe they will do a good job with the writing in DA4, but I would not use previous iterations written by different people to predict that.
Odds are pretty good the new people will have corporate riding their buttocks telling them what to do, so I have fairly low hopes for the story. On the plus side this means that it will be easy for my expectations to be exceeded.
