Bioware are redefining the RPG by turning it into, as Boo says, into Tomb Raider.
Maria makes an astute, well-observed point, WRPGs have lines in the sand. One by one Bio have eliminated them, hey they'll probably be making Final Fantasy type games within five years.
Basically, Bio are making games uniquely tailored to make me not want to buy them, it's an interesting journey made even more odd by the fact that Dragon Age: Origins was so nearly there and a good game to boot.
The pattern is familiar too - make a really good game, then five lame ones, then a good one... rinse and repeat.
