Good grief. A couple of videos and screens have been pushed out by Bioware for Mass Effect 3 in the last week, but the most interesting - for lack of a better word - is the Kinect featurette. Watch it and you'll say the words good grief again...
I cannot see the advantage of speaking the commands, then waiting to make sure the command is carried out, faster than pushing a button. It is looking very much like a tacked on feature rather than making the game a better experience. Speaking of Kinect, a friend of mine was in the middle playing Call Of Duty when his partner decided to walk in and commanded "Xbox off". See, Kinect no good to the hardcore.
