Well the turn basedness of combat was the first system we heard described but in different interviews and posts by Brad it sounded like they were revamping and moving away from that turn based combat method. If I recall it was in response to the E3 feeling that combat was too slow. Here are a few threads where he talks about the slowness and then a few weeks later mentions the overhaul. I wouldnt be surprised if you still have the ability to counterspell and what not but its alot faster paced now.
