Seems as if Steam activation is still up in the air. Lots of different opinions.

It might be the first game to have Steam only exclusive achievements w/o import. I don't know of another game like this.
It IS going to have achievements and steam cloud, just whether or not some retail keys will be importable or not remains up for debate. I've read that the D2D and Impulse will be DRM free too, like GOG, so an import does seem highly unlikely.
Strange as the store does *not* list achievements yet, but they have been slated to be there. Unfortunate for me as I unfortunately have achievement sickness right now, I'd see myself pay 15$ more for the integration, tracking, and those achievements (to show off to my friends.) Sick I know. So importing is important to me.
Does anyone know typically when the 10% falls off the pre-orders on Steam?
If I was patient and smart, in the time it takes me to finish Witcher 1, Witcher 2 will be at a better non week1/month1 price, but what fun is that?
