I like both Icewind's. They have great music and really allow you to get into the nuts and bolts of combat for the IE games. Yeah, it's soooo close to straight up hack n slash but it does not bother me.
DA 2 get's too much hate. No where near as good as most of the games mentioned here but not bad. It was just "good". Unfortunately that is not good enough.
A combination of the two? Icewind was far more combat oriented and allowed you to really get into the nuts and bolts of the engines combat. Baldurs Gate was a bit more open and exploration focused. Is this a cross of the two? Either way it looks GREAT!
