WoW didn't do anything but take a bunch of already used features and make it relatively simple and bug-free, but at some point you have to move forward and do something that breaks the mold a bit. I'd personally rather see the focus moved away from eye-popping graphics and toward a deeper game experience that you can't get by simply mixing and matching current features, I don't buy the excuse that new features are 'going out on a limb' either. There is such a thing as 'natural progression' and it doesn't mean re-skinning your models for DX10. Breaking new ground doesn't mean reinventing the wheel either when all we want is another outlet for our game habits.
