I'm probably going to buy this at one time; however I do not like a) Geralts new -ahem- image, b) the art direction c) the movie like cinematics graphics (why, oh why, do every developer think that they need to make a game's graphics similar to movies...) d) and some other stuff probably.
I do like the full voice over, though, I also like that you can actually see the full response in the (sort of) dialogue wheel, they've used. I like the sound of Geralts voice, although I find it could be a bit more cynical, and tough.
In comparison with DA2, I like DA2's art direction and graphics, but that's just because I'm more to the cartoony animations in (fantasy) games than the photo realistic movie trend...
