Personally I don't care about achivements, they are there is filler and to cater to people that like instant glorification and sense of accomplishment. But I respect those that like it, I think they will be in, they are just not listed yet and this happens in alot of other games too, nothing showcased before the game is released or close to.

Achivements sometimes takes away creativity and enjoying games to your own style. I have seen people follow a "path" even if they don't want to, just to get achivements..........
